I have, for a long time, been slowly creating my own printable templates for certain comic book boards.
And I figured, having finished the three main important ones, I'd compile them into a set and share them. This set of three templates consists of:
(1) 11x17 inch blue-line full bleed comic page template
(2) 11x17 inch blue-line full bleed comic cover template
(3) 8.5x11 inch blue-line comic layout template
You'll need to print the comic page and comic cover files onto 11x17 inch plate finish bristol, or whatever boards you do your comics on. The layout sheet template can be printed on any white paper you want to do your page layout planning on.
The files in this kit will enable you to print all the stuff you need to create a comic. The measurements and printed margins are industry standard in their aspect ratio and the non-photo blue was compared to my pro boards and the colors were spot on most varieties.
Now, a caveat on colors... These boards print a perfect non-photo blue on MY PRINTER. Every printer differs a little in how it reads colors though, and you may need to adjust the file's colors slightly to suit your printer. When creating them, I used the accepted hexadecimal color code for perfect non-photo blue--A4DDED. Your printer's mileage with this may vary.
I hope this is helpful. Please don't post these files to share anywhere else. Though please feel free to link back to here. And Enjoy! Comic creation is a joy, and I hope these help people more easily and affordably create. And if you have any questions about using these templates, just ask!
FYI, I use a wide format Epson printer to create the 11x17 boards. This kind of printer has a full bleed function (which means it prints to the edge of the board without that inconvenient border) I just load the 11x17 bristol stock in and go. If it turns out that your wide format printer does NOT print to the edge, then you may need to open the files in an editor (such as photoshop) and trim the outer negative space just a bit. Then they'll print just perfect, even on a wide format printer that doesn't have full bleed capability.
