Make your image the right size and resolution by goig going to Top Menu > Image > Image size. Make it as big as I want it to be when printed out (see Paper Store Prices or ask your professor what the max size of your transparency can be; I am using 8.5 x 11 here) and the output I want it to be for the final resolution (see the Bitmapping section below for info about resolution)

IMPORTANT

• The image resolution should be at 300 or 360 ppi.
• Print your image on Pictorico OHP Transparency film with an inkjet printer that can print high quality photos.

2/Color correction

1. Open your image in Photoshop.
2. Go to Top Menu > File > Save As (as we are doing destructive image editing) and save as a new image.
3. Add any adjustment layers you want at this time (eg. contrast, etc.) by going to Top Menu > Layer > New Adjustment Layer
4. Make sure you add at least a B+W Adjustment Layer to make your image black and white:
   1. Top Menu> Layer > New Adjustment Layer > Black & White
      
      1. Set the "Mode" to normal and opacity 100%.
         
      1. A box with some color sliders will come up. You can play around with these until your image looks good to you. Essentially, you are choosing how light and how dark Photoshop sees certain colors.

   2. When you are happy with your colors, go Top Menu > Layer > Flatten.

...

Then go Top Menu > Layer > Flatten Image.

Now we must invert our photo. Always do this last, but BEFORE you bitmap.

Let's go to our Layers menu, and then press the Adjustment icon Image Removed

Now click Invert, and then once again Flatten your image.

...

/ Make your image grayscale

1. This is different than making your image black + white. You are now telling the computer to only see black whites, and greys.

2. From the top file menu, press Image > Mode > Grayscale

   If it asks to "Discard Layers," press "Flatten"

bitmap bitmap

There are several ways to make your image a bitmap. Note that the way they appear on your screen is different than how they will appear printed out. Zoom in to see details of the dot pattern.

Option A: Halftone

Halftone has the classic newspaper/comic book style dots.

To halftone your image:

From the top file menu, press Image > Mode > bitmap

...

Option B: Diffusion Dither

Diffusion dither randomly pixelates your image and can often (but not always) give you a clearer, more "true" photo.

1. From the top file menu, press Image > Mode > bitmap.

2. In the box that pops up, keep your resolution the same (because remember, we set this in step one.) With the plate maker, we can go up to about 250 dpi. Less is fine too for a more grainy look. I am going with 200dpi.

3. Press OK and you are done.
   Final output looks like this:
   Image Removed

    Select IMAGE -> IMAGE SIZE…

   Make sure you image is the correct Width and Height for your pictorico, remembering that your transparency will need to be slightly smaller than your plate.

   1. DPI: 300 - 360
   2. Size: slightly (0.5 inches) smaller than your plate. 
4. Press ok and you're done.
