Booklet

Please Notice: We had to make our Screen printing booklet into a plan 8 ½”x 11”

format so our customers would not need to stable a booklet together. We hope you

enjoy this information. All this information can be applied to screen printing Solar

Cells on glass, plastic or metal. If you are needing more information as in large

booklet forms as well as Screen Printing supplies, then check out these companies

online at: www.silkscreenbiz.com another great supplier to check out is at:

The following photo’s are just examples of what is used to Screen Print.

Learn how to Screen Print. Screen printing is done all over the world by very large

printing companies right down to the guy who does it at home in his basement.

Screen printing was first discovered by the Chinese hundreds of years ago. It is a

very simple process that anyone can do. The Chinese first used silk to use in there

wood frames to print with, then as time went on better material was made to

print with.

We hope you enjoy this small booklet, it was thrown together very quickly for

Creative Science and Research as a help for there customers. If you would like to

learn more. your local library will have more information or any local art store.

many books have been written on this subject or see www.Silkscreenbiz.com

SO HOW DO WE SCREEN PRINT?

Screen printing is done by using a wooden frame with screen printing cloth stretched

over it, Then there is a photo emulsion applied to the screen, dried and then exposed to a

bright light source, ( You can use the sun or a photo bulb )

but before exposing it to the light source, you must first apply your film positive to the

back of screen. A film positive is simply a clear piece of plastic with a silhouette or a

profile or art work design filled in with a dark color, in this case you can use dark red or

black. Art stores and screen supply companies sell a red film you can cut with an exacto

knife called amerlith. You simply cut out your design and peel away the background that

you do not want. I suggest you go to a local screen printing shop and ask them if you can

buy a small 24” x 24” piece, it would be cheaper than buying a whole roll. Once you are

done cutting out your design on the amberlith plastic film, you then spray the front of it (

the side with the film cut on it, ) with all purpose spray adhesive, let it dry for 3 minutes or

so and then apply to back of Photo emulsioned screen and then expose to light source.

Now after exposing it to the sun, the screen is then washed out with water using a

water hose. The black or red image on the film positive did not let any sun get to the

photo emulsion, therefor the unexposed photo emulsion can then be washed out, the

other has been hardened by the sun light and can not be washed out. now after the

screen has dried. you can use it to print your image with over and over as many times as

you like.

Ink is then applied to the inside of the screen, and by using a soft rubber squeegee, you

pull the ink over top of the image area. ink then only passes through that area which was

not exposed to the sun. ( See our video ) This process is known as screen printing.

Let me give an example: The screen is like an open water valve, when certain areas of

the screen are stopped off, then the water can not go through it, only where you want it to

go.

The photo emulsion can be like this example: take a 8 1/2" x 11" piece of paper. now cut

a hole in it. now lay it flat down onto a table. Now get a can of spray paint and begin

spraying the paper. Now lift the paper up and what do you have? you have a painted

circle. This is the same way screen printing works. The nice thing about screen printing is

you can pass just about any type of liquid you want through the screen print area. If you

are printing on paper you can screen print with any type of paint or screen printing ink,

just as long as it is thick enough. If it is to thin your printed image will have run spots.

Of course there is a much easier way to make your own screen and that is to

buy one. they are not that expensive. In your Yellow page phone book look

under art supply stores and then look under Screen printing companies. Tell them

what you are doing and ask them how much they will charge for a screen the

size of a T-shirt screen, (Fine mesh-yellow or white ) and also ask how much they

would charge to coat out and expose for you. should be only about $25 for the

screen and $19 to coat out with photo emulsion and expose it for you. They are

pro's most know what they are doing.

Materials you will need

IT IS BEST IF YOU MAKE OR BUY 2 SCREENS

1- used for negative contact, nickel mesh print

2nd used for layers n-type and p-type.

Screen Printing Ink

Ink can be thick paint(oil base), or special Screen

printing ink, or in your case an Ink that you will

create to print Solar Cells with.

INK

Printing Ink can not be to thin or it will run on the

printed image. and it can not be to thick where it

will not go through the screen. By adding your

thinner or not adding thinner you can control this.

it is like thinning paint to paint a house.

Used to move the printing ink from the top of the inside of the

screen to the bottom. To press the ink through the image and

screen onto the glass or paper.

How to Screen Print

Now lets assume that the screen is all

prepared and ready. 1st- You attach the

2 x 4 to the table using nails or wood

screws. Then you take the wood screen

and lay it flat on the table, push the

back up against the 2x4, now attach the

door hinge to the 2x4 and the wood

screen using wood screws. you will

need 2 hinges one for the top left side

and one for the right top side. Now the

screen can move up and down. Now to

keep the screen up while you are

registering the glass or what ever you

will be printing on, you will need to add

a kickleg (see drawing). now lay down

the screen on top of the glass, and

move the glass around until the print

image is right over top of it or is in the

desired position. Now take some

masking tape and tape 3 pieces onto

the table right up to the glass, this will

be your registration marks which you

can then after printing your first piece of

glass or paper can place another in the

same place and print it in the exact

same spot. You can Screen Print the

Solar Cells either- or

Registration

To simplify registration we are showing the

top view without the screen. (of course the

screen should be there when registering

your item that you are going to print.) Once

you have completed registration pencil

around the glass onto the table, then

remove glass then place paper all around

pencil area on the outside so you will not

overspray the hold down adhesive. Now

spray the adhesive onto the table and let dry

5-10 minutes. This process will help hold

down the glass to the table while you are

printing so the glass will not move and you

will get a good print.
