Is it excessive to be working in 600 dpi for doing cartoon art in Photoshop?
First of all, what you’re probably dealing with is ppi (pixels per inch), rather than dpi (dots per inch). The difference is that one pixel is equivalent to several dots, because a pixel can be any colour, whereas to create an equivalent amount of graphic detail with dots requires several dots because the printer does this via halftoning with four inks. Generally you work in pixels, and the printer converts it to dots, and these days you don’t need to worry about the dots so much, just your pixels. Partly as a result, dpi is often confused for ppi (even in software interface – Photoshop had these mislabeled until a few years ago, making it mainstream) and so the terms have become hopelessly muddled. Now, 300 ppi is close to double the graphic detail of what almost any printer can print on paper, which is about right – if the printer’s print detail could match your image’s resolution, jaggies would start to become visible.
