Here is how you do it:

Here is a practice file if you want to follow along: | ||
1/ Choosing and sizing your image
The images that work best are ones that:
- have more contrast. An image with lots of greys and middle values won't turn up great. You can also add contrast in Photoshop.
- You can work with a color image, but you will eventually have to turn it into a B & W image like with all other transparency printing.
- Like with anything, the better resolution the image is, the better it will turn out. However, you can get creative with dot patterns etc. if you want to use a lower-res image.
I have chosen this photo, Untitled, by Carrie Mae Weems to work with.
Make your image the right size and resolution by 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
- Open your image in Photoshop.
- Go to Top
Menu > File > Save As
(as we are doing destructive image editing) and save as a new image. - Add any adjustment layers you want at this time (eg. contrast, etc.) by going to T
op Menu > Layer > New Adjustment Layer
- Make sure you add at least a B+W Adjustment Layer to make your image black and white:
Top Menu> Layer > New Adjustment Layer > Black & White
- Set the "Mode" to normal and opacity 100%.
- 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.
- Set the "Mode" to normal and opacity 100%.
When you are happy with your colors, go
Top Menu > Layer > Flatten.
2.1 /Curves + Levels (optional but highly recommended)
A/ Threshold
We want to make sure the lightest spot is pure white, and the darkest spot is pure black.
To do this, we are going to add a Curves Layer, and a Threshold layer by going to our Layers Window (Top Menu > Windows > Layers)
, and then clicking the Adjustment Laye
r icon from the bottom of the Layers menu.
Pick Curves
, and then click on the again and pick Threshold
. The order of your layers should be: Bottom-Photo / Middle-Curves / Top-Threshold
Darkest point
Now we are going to use the Threshold
menu to find the darkest point of the image.
This is the threshold menu. If you don't see it, select the Threshold Laye
r in your Layer Menu
and then to go Top Menu > Window > Properties.
Slide the slider all the way to the left (towards black) until you have a tiny bit of visual information left, (let's say about 1% of your photo/image. You are basically filtering out everything except the dark colors.
Your image will look something like this:
Now, select the curves layer
in the Layer window
. In the curves properties, you will select the black point eyedropper tool
(circled in peach below):
Use the eyedropper to click on a dark spot on your image. I clicked on the woman's hair. Then, slide the left/black curves slide
r (circled in purple) all the way to the left. You will maybe notice that more parts of the image show up. Here is a quick video:
Lightest Point
Now we are going to do the same thing but for the whites.
Go back to the Threshold properties
and now slide it as far right as you can while still seeing some parts of the photo (let's say about 1% of your photo). Now you will have something that looks like this:
Now, select the Curves layer
in the Layer window.
In the curves properties, you will select the white point eyedropper tool
(circled in blue below):
Use the eyedropper to click on a light spot on your image. I clicked on the ceiling light. Then, slide the right/white curves slider
(circled in green) all the way to the right.
Sometimes, you won't see much of a change. That's ok! It means you had a lot of contrast to begin with.
You can play around with the midtones on the curve slider, too, now if you would like to.
B/ Check values (optional, but helpful!)
Now go to Top Menu > Windows > Info.
Use the dropper to go to the light and dark parks of your image. Hopefully, the whitest white is 0% for all CMYK colors. Rarely will your black be completely black, but we are looking for around 90% K value.
White:
Dark/black:
C/ Flatten
Now you can delete your Threshold Layer
(but keep the curves layer!)
Then go Top Menu > Layer > Flatten Image.
3/ Make your image grayscale
- This is different than making your image black + white. You are now telling the computer to only see black whites, and greys.
From the top file menu, press Image > Mode > Grayscale
If it asks to "Discard Layers," press "Flatten"
5/ Size your image
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.
- DPI: 300 - 360
- Size: slightly (0.5 inches) smaller than your plate.
- Press ok and you're done.
6/ Save + Upload your image
- Press
File > Save As
- Name your file and save as Photoshop (PSD) on the Format menu.
- To print your transparency: Ask your teacher where they want you to save your final file. If unsure, save on your USB drive, or to the Short-Term Storage Box Folder.
- Personal Backup: Files will automatically delete from the school computer when you are logged out. If you are on a shared computer, make sure to save a backup for yourself by: emailing to yourself, uploading to a cloud service, putting on a personal USB.
Print!
You can either have your transparency printed by your professor or TA in the print office on the Epson 3880 (there are size limits on what we can do). See Paper Store Prices for current price and size limitations.
Or, you can get it printed at Graphic Arts (cash/cheque only!)
