UPDATE: I've fixed up the measurements. The Photoshop file now uses guides for accurate measurement, and the Illustrator files have more exact measurements because I used the ruler tool in the Photoshop file. Only problem with Illustrator was the program always rounding numbers up to the nearest whole value.
Okay. I should explain this just in case people don't know comic book terms.
The one problem I've been having with sketching comics in Photoshop and inking in Illustrator (then taking it back to Photoshop for colouring) is keeping the page the same size (the standard comic page size). So I thought this would work. Having a .psd file and an Illustrator template of the SAME size to prevent distortion.
This file is the standard dimensions of a traditional comic book page sold in the U.S. The zip include a Photoshop file template (400DPI because that's the standard, if you're doing the lineart digitally, start at 600DPI) and two Illustrator templates (a single page and a spread).
Overall area - 6.875" x 10.438" (17.463cm x 26.513cm)
Trim size - 6.625" x 10.25" (16.826cm x 26.04cm)
Safe area - 5.899" x 9.075" (14.983cm x 23.050cm)
Now for essential information. The whole image/canvas in Photoshop (which is everything up to the red boarder in Illustrator) is the entire page PLUS BLEEDS. Bleeding is when a comic artist wants to be creative and have a panel or two extend off the edges of the page. Yes, you have to colour the bleeds too, or else you'll get unsightly white areas that you might have missed around the edge of the page.
The first boarder in Photoshop (the outer one, which is basically the edge of the art board in Illustrator) is the trim size, the finished size of the page once the bleeds have been chopped off in the presses. In the end, the page will be this size.
Finally, the inner black boarder in the SAFE AREA (or sometimes also known as the live area). Let's face it. Printing presses are not perfect (yet). You have to be prepared in case the plates slip and more of the page gets chopped off than you intended. Also, don't you hate it when you're reading a thick graphic novel and there's something interesting or important squished in the binding of the book, and you have to almost rip the book apart to see what it is? The safe area is an area that is guaranteed to not be chopped off in the presses. This is the area where you should fit all the speech bubbles and important elements in your comic so the reader isn't left confused.
So enjoy it, and I hope it helps out with your comics.
(Just to be sure, you don't need to use any template if you're making a web comic and have no intention of printing it. Web comics can be of any size and shape because they're just images)
