ho to make stencil with photosop

A stencil is a thin sheet of material, such as paper, plastic, or metal, with letters or a design cut from it, used to produce the letters or design on an underlying surface by applying pigment through the cut-out holes in the material. The key advantage of a stencil is that it can be reused to repeatedly and rapidly produce the same letters or design. The design produced with a stencil is also called a stencil. The context in which stencil is used makes clear which meaning is intended. Although aerosol or painting stencils can be made for one-time use, typically they are made to be reusable. To be reusable, they must remain intact after a design is produced and the stencil is removed from the work surface. With some designs, this is done by connecting stencil islands (sections of material that are inside cut-out "holes" in the stencil) to other parts of the stencil with bridges (narrow sections of material that are not cut out).
Stencil technique in visual art is also referred to as pochoir. A related technique (which has found applicability in some surrealist compositions) is aerography, in which spray-painting is done around a three-dimensional object to create a negative of the object instead of a positive of a stencil design. This technique was used in cave paintings dating to 10,000 BC, where human hands were used in painting hand print outlines among paintings of animals and other objects. The artist sprayed pigment around his hand by using a hollow bone, blown by mouth to direct a stream of pigment.
Screen printing also uses a stencil process, as does mimeography. The masters from which mimeographed pages are printed are often called "stencils." Stencils can be made with one or many colour layers using different techniques, with most stencils designed to be applied as solid colours. During screen printing and mimeography the images for stenciling are broken down into color layers. Multiple layers of stencils are used on the same surface to produce multi-colored images.

History

Paintings where the hand was used as a stencil, in a cave in Argentina

Stencil paintings of hands were common throughout the prehistoric period. Stencils may have been used to colour cloth for a very long time; the technique probably reached its peak of sophistication in Katazome and other techniques used on silks for clothes during the Edo period in Japan. In Europe, from about 1450 they were commonly used to colour old master prints printed in black and white, usually woodcuts.This was especially the case with playing-cards, which continued to be coloured by stencil long after most other subjects for prints were left in black and white. Stencils were used for mass publications, as the type didn't have to be hand-written.

How to using halftones in photosop

Step by step Photoshop coloring method using halftones.

I am making a step by step process of coloring my line work, starting now, so this may take a while! Hopefully this may help someone.



STEP 1:
You need your artwork to be at the printing size you want on the tshirt. My image size here is 12x19 inches at 300 dpi.
As shown, you need to have your line work on a layer by itself. Note that only black is present on the layer, no white or any other color.
If you draw scan your artwork in, you can use the super handy photoshop action here:

Running this action will give you a layer that isolates your art on a separate transparent layer, like in the picture above.

Step 2.


Ok your linework is isolated without any colors.
In your layers palette, click on the new layer button, and make sure you drag it below your layer with your linework.
Now select a neutral gray color in your color picker and press ctrl+backspace (you can also use the paint bucket tool) to fill the entire layer you just created with the gray color.

Step 3.


In this stage I am going to add my highlights to my image. I am not concerned with colors yet, because getting the values right is more important.
First, create a new layer right above the gray layer.
Click on the layer to make it active. Now choose black in your color picker. Next in the brush setting make sure your opacity is set to around 15 percent.

Ok start painting the highlights in.
Even though it looks like i am painting shadows, these will actually be highlights where the light is hitting. For the sake of the tutorial, i'll just do the fox and surrounding area.
With the low brush opacity, you will be able to layer the brush strokes so that you get a pretty smooth tone.

Step 5: halftoning



Ok now I am ready to turn my highlights into halftones.
First hold down ctrl and click on the thumbnail of the layer that you just painted on. You should get the "marching ants" showing that you have made a slection.
With the selection still active, open your channel palette and make a new channel. rename it to "highlights"

Press alt + backspace to fill the slection with white. Now deselect everything by pressing control+d. Go to filter-pixilate-color halftone.



Put in the settings as shown. a bigger max radius makes your halftone dots bigger. I like around 7 or 8 at this size.


Now you should have a set of halftone dots on the "highlights" channel.

Step 6


Click the top channel's eye to make all the rgb or cmyk channels visible. Click the eye of the highlights channel to hide it.
Next go to the layers palette (f7)
Step 7

now make a new empty layer above the layer you painted, and delete the layer you painted.

Step 8

Go to select, load selection, and click on the channel you created in the drop down menu

Step 9
pick a color you want to use for your highlights, and press ctrl+backspace to fill your selection with it.
Step 10

Halftones are now done. The process is the same for the shadows. Underneath the linework, highlight and shadow layers you can paint your other colors
