Colour separations (manual)














Open publication - Free publishing - More bitmap

I will talk about how these were done in a seperate post, but I am stoked that this 'CMYK bitmap' emulation has worked as well as it has on screen. Print could be a whole different kettle of fish because screens always create new patterns out of the pattern created because of the cells in a visual display. (unless its amazing, which mine aint.) I have literally ust noticed an error in the cassette  image... no type. this exclusion was totally unintentional, but gives me a chance to see what adding the type after in indesign would do to the cover. I presume adding it after would make the type alot more readable as it isnt and comprised of an outside edge of cmyk dots.

Also a quick mention about the concentration of CMYK in the separations, it varies as the amount of dots are less concentrated depending on the images saturation of that process colour in question. (compare the cyan chihuahua imge to the cyan brain image.)

Anyway, this process was done for all 12 images, very time consuming!! but after 4 images doing it the hard way, i realised theres a massive corner i could cut here. In the actions panel on photoshop you can basically record a set of actions, save them and then play them back onto another image to get exactly the same results. Ive pulled this from an online tutorial to exaplain in a more comprehensive way:


Actions Palette
Notice the arrow at the top right of the actions palette. This arrow brings up the actions menu shown on the right.
Actions MenuClick the arrow to bring up the menu and choose New Set. An action set can contain several actions. If you've never created actions before, it's a good idea to save all your personal actions in a set. Give your new Action Set a name, then click OK.
Next, choose New Action from the menu. Give your action a descriptive name. After you click OK, you'll see the red dot on the actions palette to show you're recording.
Recording an Action
For this example I'm going to record an action to rotate an image. Go to edit and choose the rotate command, then go to the actions palette and hit the stop button (the black square).
Now you have an action!
To use the action in batch mode, you would go to File -> Automate -> Batch. You'll see the dialog box below:
Photoshop's Batch Command options
In the dialog box, simply select the set and the action you just created. For the source, choose the folder that contains the images you want to process. For the destination, choose another folder for Photoshop to output the rotated images. (You can choose "Save and Close" to have Photoshop save them in the source folder, but I don't advise it... it's too easy to make a mistake. It's much safer to use two folders and then delete the original files after you've made sure your batch processing was successful.) For errors you can either have the batch proccess stop, or create a log file of the errors. When you hit OK, you can just sit back and watch while Photoshop does all the work for you!
Once you have an action and you know how to use the batch command, you can use it anytime you have several photos you need to rotate. You could even do an another action to resize a folder of images.

So there you have it, batch processing and action recording, thanks to :
