Two-Coloring Proofs. 4. Odd Dissections of a Square. 5. Enumerating the Rationals. 6. Kneser's Conjecture. 7. Places. The Book, as promulgated by Paul Erd˝os, is God's collection of the most elegant proofs of any and all mathematical theorems, including those still to be.

Many people still prefer to check on paper rather than on screen. These proofs are not intended to show colour accurately, nor image quality, nor paper quality. As with softproofs print-ready files are processed through our prepress software before being output so that any potential issues can be spotted.
There is no need to return laser proofs to Gomer prior to printing.
Inkjet proofs aka Epson proofs, aka digital cromalins, aka press proofs aka Sherpas These proofs are colour calibrated to the press and highly accurate for colour and image quality but not necessarily paper. Inkjet proofs should be returned to Gomer prior to printing so that they can be matched to on press.
If you have concerns about colour or image quality, outputting a few pages to inkjet proof before printing is a very good idea. Wet proofs These are the most expensive and most accurate form of proofs.
They are expensive because they are printed on the B1 XL press on the actual stock that will be used on the job and using the specified coating if applicable. They are therefore accurate for content, colour, image quality and paper stock.
Because of the cost we only rarely output this type of proof. When it is necessary we can output images rather than pages from the book, so that more content will fit on a B1 sheet.
