    PREPARING A WORK AREA

    A card t able will provide enough work area for most projectsis necessary to locate your work area with easy access to a larsink or laundry t ub wit h hot and cold water.

    If you plan t o make a large number of print s, you may wishstring a line through spring-type clothespins or bulldog clips,make a rack to keep prints from smearing while they dry.

    PREPARING YOUR TOOLS

    Step A

    Two hinges wi th screws and removable p ins are included in somSpeedball kits. These are easily attached by first joining thalves together wi th hinge pins. It is best to mount the side of thinge with two bearings to the base and the side of the hinwith one bearing to the screen frame. Then, position tassembled hinges over the pilot holes on t op of the f rame abase and screw them in place. Be sure they are right side uSpeedball off ers heavy duty h inge clamps for bigger screens (slist of products on page 10). Follow this by screwing the kicklto t he side of the frame. A pilot hole has been provided for thalso. Note the kickleg should be free-swinging.

    Step BThe next important step in preparation is to detach the frafrom the base and scrub both sides of the screen fabric witnylon brush and trisodium phosphate/water or dishwashpowder/water solution.

    INTRODUCTION

    Screen-printing, sometimes called silk screening or serigraphy,has long proved its worth as a fine arts and commercialmedium. While SPEEDBALL Screen Printing Materials meet thehigh quality standards of professionals, our hope is to bring thesatisfaction and enjoyment of Screen Printing to the hobbyist,the handcraft er and t he student as well.

    The Speedball

    systems allow total flexibility. You can createscreen stencils in a variety of ways and produce print s wi th t hreeSPEEDBALL water-based, solvent-free inks; water-soluble,permanent acrylic and f abric inks.

    These instructions have been prepared in simple language. Iffollowed, they will produce satisfying results. Additional andreplacement materials are available from all stores whereSPEEDBALL Art Products are sold.

    In addition to the materials supplied in the SPEEDBALL Kit s, you

    may want t o have the f ollow ing it ems on hand:

    Step B

    Position printing paper under the frame. Lay your cutouts this paper as desired and lower the screen

    Step CFollow t he direct ions found in sect ion Making Print s. Prdown on the screen frame to insure complete contact with cutou ts. Make your f irst print . You w ill f ind w ith the f irst passthe squeegee, the ink will cause the cutouts to stick to underside of the screen creat ing a stencil eff ect.

    Once you see how simple this method is, you may wish to variations by creating two or three designs with torn papervarious shapes and printing each in a different color or hue. not overlap cutou t pieces on t he screen.NOTE: Generally ten to fifteen prints can be satisfacto

    produced by this method. When a larger number of prints adesired, you should use one or more permanent methods

    #2 SCREEN FILLER METHOD(Direct block-out or Negative Met hod )

    Using Screen Filler is another simple means of preparingscreen for printing. The Screen Filler is used to block out thoareas that you do not wish to print. This allows the ink to forced through the screen wherever the Screen Filler has nbeen applied.

    Step AOn a sheet of plain paper, make up t he illust rati ons or messayou wish to print with your screen. Place this layout ontabletop. Place your screen over this layout and trace yodesign directly on the screen f abric using a soft lead pencil.

    Step B

    Stir the Screen Filler until it is thoroughly mixed to a smooconsistency. Using a paintbrush, paint the screen filler on areas of your layout that you do not want to print. Be certthat the bottom of the screen is elevated (not touching ttable). When all areas to be blocked ou t are covered w it h Scre

    Filler, flip the screen over andsmooth out places the Filler mayhave collected on the oppositeside of the screen. Be carefulduring this smoothing outprocess not to distort yourwork.

    Screen Printing Instruction Booklet

    Let it dry thoroughly after rinsing. For water-based inks, use 1wide water-resistant masking tape. Lay the tape so it is dividedequally half on the screen fabric-half on the screen frame. Turnthe f rame over and cover t he groove wit h t ape. Be certain t hatthe tape extends beyond the frame and onto the fabric. Forsolvent-based inks, use seal gummed water-soluble tape withseveral coats of polyurethane.

    Taping in t his way helps to maintain a tigh t screen, and

    prevents ink from leaking under the screen frame duringprinting and will keep the edges of your prints clean. To getmaximum adhesion of the tape, rub it wit h a spoon or w oodenstirrer. When choosing your pattern or design make sure toleave a generous border from the taped edges(minimum of 1from t aped edge).

    Step CThere are a number of ways to prepare a screen to print thepicture or message you want. While the methods are different,the basic principle is to make a stencil on t he screen f abric wh ichallows ink t o be forced through it s open areas to produce adesign.

    PREPARING SCREENS

    These instructions explain 4 of the more popular methods usedfor preparing screens. Read and Follow them carefull y.

    #1 PAPER STENCIL METHOD

    This is the best method for a beginner. It is the fastest, leastexpensive, and simplest way to prepare a screen. The Paperstencil method i s good fo r geometri c shapes and basic patt erns.It is not intended for complicated designs or lettering. Begin bycut ting an illustrat ion f rom paper. Keep the paper flat and notwr inkled. For more accurat e and du rable cut paper stencils, usefreezer w rap (shiny side up). Designs can be cut with scissors or

    stencil knife or they can be torn to create a texturedappearance.

    Step ACut your paper stencil. You may wish to create a design byfolding and cutting your paper as illustrated. For your stencil,you can use either t he cut out or t he paper remaining.

    Step CLeave the screen to dry in a level position. Make sure nothingtouches the areas covered with Screen Filler. Thorough drying isnecessary. Overnight drying is recommended to assure bestresults.

    Check f or p inho les in t he blocked-out areas. You can do this byholding the screen up to a light. Fill any pinholes with ScreenFiller and allow to dry completely. You are now ready to print.

    NOTES: Since Screen Filler is applied to all areas which are not tobe printed, this along wit h all traditi onal direct methods - isconsidered to be a negative method of print ing. Your print w illbe the opposite of that which you created in your screen.

    #3 Draw ing Fluid Screen Filler M ethod(Tusche resist or posit ive method)

    Step A

    On a sheet of plain paper, make up the illustration or messageyou wish to print with your screen. Place this layout on atabletop. Place your screen over this layout, top side up. Trace

    your design directly on the screen fabric with a soft lead pencil.

    Step A (alternative)The preparati on of a layout is to help guide t he application ofDrawing Fluid. If you feel such a guide is unnecessary, godirectly t o Step B.

    Step BYou can w ork on either side of the screen. Remember, however,that your printing will be done from the top (or ink-fi l l ) sideof the screen.

    Be certain that the screen is elevated not touching the table.Using a paint brush, paint t he Drawing Fluid over those areas ofyour layout t hat you w ant t o print . Leave the screen t o dry in alevel, flat position. Make sure nothing touches the areascovered with Drawing Fluid.

    Step CAf ter the Drawing Fluid is completely dry, open t he Screen Fillerand mix it thoroughly to a smooth consistency. Spoon it ontothe screen fabric on the same side of the screen used for theapplication of Drawing Fluid.

    Use the squeegee or the plastic spreader to apply an evenly

    smooth coating over the entire screen. Make only one pass.Mu lt iple passes of Screen Filler w ill dissolve t he Drawing Fluid andprevent character washout. Regular scoop coaters are available

    through screen pri nt ers suppl iers.

    Again, put the screen to dry in ahorizontal position making sure

    nothing t ouches the f abric. It isimportant that the Screen Filler

    dries completely.

    Step DWhen the Screen Filler has thoroughly dried, spray cold waon bot h sides of the screen. Concentrat e the spray on t he arwhere Drawing Fluid was applied. These areas wi ll w ash ou t athe screen w ill open at those points so t hat ink can flow throuthem. If some areas remain slightly blocked, scrub them lighwi th a small st if f b rush on bot h sides.(An old toot hbrush will a great job.) If necessary you can use Greased Lightning Washing Soda (an Arm& Hammer Product) Washing Soda mu

    be dissolved in warm water (1 cup per gallon of wat er). DO NUSE HOT WATER DURING THIS STAGE. Allow your screen to dry inlevel (horizontal) posit ion, bot tom-side up. Using a hair dryerfan may accelerate drying time. Move to the section mark Making Prints .

    #4 PHOTOGRAPHIC EM ULSION M ETHOD

    Use polyester screen f abric. Nylon wi ll stretch wit h w ater-basinks and is not suitable. Do not use silk or organdy if you wto reclaim t he screen.

    This is one of the most exciting methods of Screen Printbecause it offers the widest range of possibilities. It mapossible the printing of fine line drawings, various hand acommercial lettering techniques, as well as photographalf-tone positives.

    All methods of photographic Screen Printing require thrthings: (1) A screen prepared with a light-sensitive coati(2) A film positive, or equal. (3) A light source that will enayou to transfer the opaque images on your positive to tligh t -sensit ive stencil you have prepared.

    Step A Mixing the photo emulsion

    Diazo System: Follow the mixing instructions given on bocontainers. Store the sensitized emulsion in a cool and daplace. Shelf lif e for the sensit ized emu lsion is 4 weeks at 90

    weeks at 70 F, and 4 mont hs when ref rigerat ed.

    Step B Coating the ScreenCoat the screen by firstpouring a bead of thesolut ion on one end ofthe bottom side of thescreen. Spread it evenly andthinly with the squeegee orthe plastic spreader. Use moresolution where necessary. Pour a bead of the solution on one

    end of the inside of the screen and spread it evenly with thesqueegee or the plastic spreader. Work to achieve an evencontinuous coating on both sides of the screen fabric. Performthe final spreading on the inside of the screen. Return anyexcess solution to your mixing container. Be careful to clearaway any extra drips of solution to obtain proper exposure.

    Step C Drying the coated screenIn an area AWAY FROM LIGHT AND HEAT, set the screen to dryhorizontally, bottom side down. This will provide the most even,flat fil m on the underside of t he screen. It w ill, however,require your elevati ng t he four corners of the underside of theframe during the drying stage wi th push pins or other suitable

    devices. An empty drawer, cupboard, closet, or under acardboard box will work fine. Allow the screen to drythoroughly. If more than 300 prints are to be run, it is best toapply a second coating of the sensitized Photo Emulsion to thebottom of the screen after the first coat is dry. Remember, workfor a smoot h even THIN coat ing. Repeat t he drying process awayfrom heat and light.

    Once the sensitized screen is dry, it must remain in a darkenedarea until it is ready to be exposed. A fan in the dark area willgreatly speed up the drying of the emulsion on the screen.

    Step D Preparing a positive

    With Speedballs Diazo System, the maximum allowable timebetween application of the sensitized emulsion to the screenand the exposure is four weeks at room temperature, in acompletely dark environment.

    A positi ve is any opaque image (usually black), on anytransparent or translucent surface. There are many ways youmay choose to prepare them.

    An excellent transparent f ilm f or t his purpose is prepared acetateor wet media acetate. The printed sheets (positives) have copyand illustrations that may be used to create a picture or message.With the plain sheets, you may make artwork of your own withSpeedball Super Black Ink and an artists brush, Speedball

    Drawing Pens or enamel paint pens. Excellent result s can also beobtained by using dry transfer, or pressure sensitive letters andsymbols. These can be applied directly on the tracing paper orclear plastic. The graphics must be opaque to light. Natural itemssuch as leaves may be used between the glass and stencil.

    Another way of producing positives is through copy machinesthat have the capability of reproducing very opaquely on film,

    tracing paper etc. In order to satisfactorily produce a positusing a copy machine, the following conditions must be met: Black and White line work. (2) Must be opaque Photograpprint. (3) Must have high contrast.

    For an in-depth treatment of photographic screen procedurwe hig hly recommend t he book Screen Print inCont emporary M ethods and Materials by Frances and NormLassiter. This book is available at most artist materials stores.

    Using a desktop computer, you can download many copyrigfree images suitable for screen-printing from any simpgraphic program. You can print that image directly on transparency material. You can also make copies on a copthat w ill accept t ransparencies.

    IDEA: To get a bold solid image, t ry making 2 copies of the saimage on transparencies. Match the designs and tape togethfor use as a positive.

    Step E Light Source

    The BBA No.1 Bulb is preferable, particularly for fine graphi

    because the exposure time is less. To set up your Light Stat ioplace the screen on top of a piece of black paper and cente12 inches directly below a 150W clear incandescent bulb oBBA No.1 Photoflood Bulb. You can also use a light table w20W florescent tubes. Either should be fitted with a reflecshop ligh t.

    Unfi lt ered Black Light tubes wi ll cut exposure t ime considerabMaybe as little as 3-5 minutes. You need to test for accuracy.

    The positive can be placed in contact with the coated (dscreen by either of the above methods.

    Step FBefore you remove the sensitized screen from the dark dryarea, make sure everything you need to print with is on hanSet up your exposure lamp as described in Step E. Copy aillustrations (positives) can be fixed in place with cellophatape. Do not let two layers of tracing paper overlap. A betalternative than t aping the posit ives to the screen fabric islay a piece of clear glass, Lucite, or Plexiglas on top of them. Oof these must be used if t hin li nes or let tering less than 1/4 is to be print ed. Whichever you use, onceyou are sure all posit ives are in placeand flat against the fabric, you are readyto expose the screen. A screen usingpositives made with tracing paper andIndia ink could now look something likethis:

    PLEASE NOTE: This chart has been prepared using an aluminumfoil pie-plate reflector as indicated in our instructions. Moresophisticated light sources, reflectors and equipment can, ofcourse, be used. (See previous note) However, as any variable ischanged, you will have to adjust the exposure times and

    distances. This will require experimentation through the use oftest strips or other light testing devices or procedures. Turn onthe light and note the time. Expose according to time anddistance indicated in chart. After exposure remove positive andtake screen to sink.

    Step GApply a forceful spray of water (body temperature) to bothsides of the screen. DO NOT USE HOT WATER. Concentrate thisspray on the light images on the topside of the screen. After afew minut es, th ese areas wil l become open . Cont inuespraying until all unwanted emulsion is gone. Perform finalspraying with cold water.

    Once you have completely washed the screen, let it drytho roughly in a level flat position.

    Hold the dry frame to the light and check for pinholes.These can be covered with Speedball Screen Filler or pieces ofmasking tape stuck to the bottom of the screen. If Screen Filleris used, let the screen dry again.

    Follow the directions found in t he section Making Prints .

    NOTE: Photo Emulsion should not be left in the screindefinitely unless a permanent stencil is wanted. It should washed out as soon as the run is completed. See Clean-inst ructions on page 6.

    MAKING PRINTS

    Step A: PreparationsAttach your screen frame to the base by inserting the hinpins. For off-contact printing tape a penny or a nickel to eachthe f our corners on t he underside of the screen. Place a sheetyour print ing paper under the screen and posit ion it as it i s to

    print ed. Allow f or margins. When you are certain t hat t he pais in the correct position, lift the screen gently and mark wheach edge of the paper should be placed.

    Cut three pieces of cardboard about 1 x 2 and use these registration guides. Place these next to the lines you drew the base so you can correctlylocate each sheet t o be prin ted.

    These guides should befastened securely with tape orrubber cement . Good guides areparticularly important if youintend to print more thanone color on any print.

    Step B Selecting Inks for Printing on Paper

    WATER SOLUBLE INKSArt prints require porous-surface papers of high quality. (Wrecommend 100% rag or heavy paper f or best result s.)For moother printing applications, construction paper, drawing papcharcoal paper, pastel paper, most board it ems(except railroboard) and cover stock (especially good f or greeting cards) wbe fine. Ink remains water-soluble after drying.

    Avoid slick coated, high gloss papers or vinyl or plastic coatpapers.

    Stir the ink completely until you achieve a butt ery creamy consistency. If t oo t hick, add one or t wo dropswater or Water Soluble Transparent Extender Base. Mthoroughly. Colors may be intermixed. Water Soluble ExtendBase may be used t o make the colors more t ransparent .

  • 7/31/2019 Speedball Screen Printing Instructions

    7/12

    PERMANENT ACRYLIC INKSFine art prints require smooth matte finish, medium or heavyweigh t papers. To overcome buckling caused by wat erpenetration, after each color run is dry, place a flat weight onstacked pri nt s. This wi ll cause t hem t o d ry f lat and is especiallyimportant for good color registration.

    These water-based acrylic inks dry water resistant.

    To achieve transparency or economy, SPEEDBALL

    Extender Base(preferred) or Transparent Base may be added. Never add more t han

    10-15% Transparent Base. Do not allow ink to dry in screen.

    For most other printing applications like posters, greeting cards,book covers, etc., 20# weight and thicker cover stock paper isrecommended.

    Avoid slick coated, high gloss papers or vinyl or plastic coated papers.

    Stir the ink completely unt il you achieve a but tery or creamyconsistency. If too heavy or thick, add one or two drops of water,SPEEDBALL Acrylic Extender Base or SPEEBALL Acrylic

    Transparent Base. Never add more than 10-15% Transparent Base.Mix thoroughly.

    Step B Alternat iveSelecting inks for printing on non-paper surfaces.

    WATER SOLUBLE INKS These can be used on wood or masoniteif first coated with an acrylic emulsion base coat such asSPEEDBALL Gesso. To achieve water-resistance, use an acrylic aspray fixative or a solvent-based varnish as a topcoat.

    FABRIC INKS These can be used on almost any fabric that can besubjected to a hot iron (275 375) Do not use on non-porous

    fabrics such as nylon.

    ACRYLIC INKS These inks can also be used on wood, masoniteand many coated surfaces. Always pre-test befo re using.

    Step C Printing on Paper

    Spoon t he ink across the end of the screen nearest to you. With t hescreen lifted slightly from the base, apply an even blanket of ink

    onto the print area. Be sure to use an easy, smooth stroke with thesqueegee at a slight angle away from you. This is the flood stroke.Drop t he screen onto your paper. Lif t the squeegee over the r idge of

    ink and make the print stroke by pulling towards yourself. Keep thesqueegee at a 45 angle w ith enough pressure t o scrape the ink from

    the screen. Lif t the screen from t he prin t, make t he flood stroke, setthe kick leg, remove the print and put it to dry on your rack or l ine.

    Insert new paper, release the kick leg and repeat the process.

    Sharp clear prints can be produced provided you (1) maintain an

    adequate quantity of ink on the screen, (2) use the flood stroke butsparingly. For more detailed images avoid the flood stroke, and (3)

    maintain adequate and even pressure on the squeegee during pr intstroke.

    Step D Clean upAf ter you have made your print s, remove any remaining inkthe screen. This ink can be saved if you wish. Detach the frafrom the base (dont lose the hinge pins). SEE SECTION OCLEAN-UP.

    PRINTING WITH FABRIC INKS

    For the most part, screen-printing on fabric is the same printing on paper. Use only fabrics that can be subjected temperatures of at least 275 - 375 F. Do no t use on non-porofabri cs such as nylon. Pre-test all f abrics. Fabrics wit h sizing mbe washed prior t o pri nt ing. This wi ll assure proper adhesionthe fabric ink to the fabric.

    Five important differences are:

    1. The screen f rame is usually detached from t he base andused alone. Usually two (2) people should work on theprinting process one holding the screen frame tightlyagainst t he fabric, and the other doing t he printing.

    2. On articles like T-shirt s, a piece of f oamboard or paper mbe put inside each garment to act as a barrier.

    3. To improve the lubrici ty (slipperiness) of the ink, you maadd t he Transparent Base. To slow drying or to preventscreen clogging, add the Retarder Base (1-2 Tbs of 8 oz. of in

    4. Wash-up of screens and tools must be done immediatelyaft er use. If t hey are allow ed to dry on your screen or t othey are diff icult or impossible t o remove.

    5. Aft er the fabric ink dries on the fabric, set a household iat the highest dry heat (no steam) that will not scorch thfabric and wi th a cloth or paper between t he iron andprint ed material, iron on each side for 3 to 5 minut es.This will make the ink withstand repeated washings.

    IM PORTANT: PRE-TEST SAM PLES PRIOR TO ALL PRODUCTION RUNS

    inadequate wash fastness occurs, the print needs to be heat longer.

    MULTI-COLOR PRINTING

    Multi-color signs can be achieved easily by making one scre

    wi th t he ent ire message on it . Prepare the screen by any methyou prefer. Once the screen is ready, simply block the words ydo not want to print with your first color by putting maskitape or paper on the bott om side of the screen fabric.

    Af ter you have made your first run of print s, wash t he ink f rthe screen and let it dry. Follow this by blocking-out the woyou just printed and unblocking words you want to print wyour second run of color.

    8/12

    Af ter you have made this second run, again wash t he screen andlet it dry.

    Repeat the blocking and unblocking process and screen washingfor as many colors as you w ish t o run.

    Making multi-color prints of detailed artwork requires themaking o f a screen fo r each color to be prin ted.(Some books onthe subject are listed later.) One way is to have these screensprepared bef ore you start to print . Addit ional Speedball framesare available. Another way is to remake or revise the originalscreen for each color to be printed.

    One interest ing ef fect can be made by having t wo (2) color p rinton overlapping areas. These overlaps can add a t hird (darker)value to the print. Speedball Transparent or Extender Bases areformulated to enable Screen Print ers to achieve th is.

    Registration guides are very important when print ing w ith morethan one color. Details on registration guides are given in stepA on the Making Print s section.

    SCREEN CLEAN-UP

    An organized work area will make clean up easy. Here are therecommended procedures:

    Water Soluble InksUse warm water and a soft brush. These inks will remain

    wat er-soluble even aft er tho rough drying.

    Fabric and Acrylic InksWASH IM MEDIATELY AFTER THE LAST PRINT IS PULLED. Use warmwater and a soft brush.

    Should ink dry in the screen, spray with Windex or a similarwindow cleaner. Rub with a lint-free cloth. When ink isremoved, wash with a mix of warm water and dishwasherdetergent (Cascade, etc.) using a soft brush. Rinse with warmwater.

    Drawing FluidWash with cool water.

    Screen Filler

    Greased Lightening or Comet cleanser is preferable removing screen f iller. One (1) cup of Arm & Hammers WashiSoda dissolved in one (1) gallon of water is also suitabInst ructions are:A. Apply to both sides wit h a paintbrush. Scrub wit h a nylo

    bristle brush.B. Apply again to bot h sides. Let stand in a horizontal positfor three to five minutes.

    C. Scrub wit h a nylon bristle brush while spraying wit h aforceful stream of hot wat er.

    Photo EmulsionPHOTO EMULSION SHOULD BE WASHED OUT OF YOUR SCREEN

    SOON AS YOUR PRINT RUN IS COMPLETED UNLESS YOU WANT

    PERMANENT STENCIL.

    ADULT SUPERVISION IS RECOMMENDED FOR THIS PROCEDURE. WE

    RUBBER GLOVES AND SMOCK.

    Photo Emulsion Remover Method:

    Be certain all of the ink has been removed from the screfabric. Apply SPEEDBALL Photo Emulsion Remover liberallyboth sides of the stencil using a paintbrush. Immediately scrboth sides of the stencil with a dry nylon bristle brush. Agaapply SPEEDBALL Photo Emulsion Remover liberally to bosides of the stencil. Keep the screen in a horizontal position three (3) minutes. Scrub both sides with the nylon bristle bruand f lush w it h a hard spray of hot wat er. Once you have startremoving Photo Emulsion you must not let the screen dry ucompletely clean.

    Possibilities:A. Screen fabric dirty.B. Screen may have been used wit h solvent-based materials or

    the sizing may not have completely washed out of thescreen fabric.

    C. Scrub wi th a sof t bri stl e brush and a dishwasher powder /water solution. Rinse well.

    Problem: Photo Emulsion will not wash out to create a stencil.

    Possibilities:A. Artw ork not prepared with a visually or photographically

    opaque material.B. Heat as well as light w ill set the photo emulsion. There

    must not be any heat build-up (above 105F) on the stencilduring exposure.

    C. More than 12 hours(at 70F) exposed before the sensitized

    screen was exposed (Speedball

    Bichromat e System).D. The sensit ized screen was exposed to too much light or heat

    before exposure to artw ork.E. Overexposure. The instructi ons list exposure t imes and

    heights fo r a disposable foil pie tin reflector. Moreeff icient ref lectors will require a higher bulb height and/orless exposure t ime.

    F. Artwork did not make proper contact with screen.G. Incomplete washout.

    Problem: Too much or all Photo Emulsion washed out of screenafter exposure.

    Possibilities:

    A. Improper mixing of emulsion and sensitizer.B. Underexposure.C. Tracing paper or f ilm not sufficiently transparent.D. Washout temperature was too high.E. Screen not dry before coating.F. Screen not dry before exposure.

    Problem: Some small details on Photo Emulsion screen did not
