I have a black and white book with about 30 images. Many are screenshots of X11 clients or X displays. I had Lulu print-on-demand print a copy so I could see the images and many were blurry.
I read at the Lulu website (http://www.lulu.com/help/index.php?fSymbol=make_sure_pdf_prints_right) the following: - Do not downsample your images unless they are fully rasterized. If they are fully rasterized and the DPI is greater than 300, downsample to 300 DPI. - Image compression should be set to ZIP if you want lossless (no artifacts/distortion-free) images. To reduce filesize, use JPEG -> High. - If you are printing a color book that has black & white images in it, the black & white images should have the colorspace set to grayscale. - Leave the images' colorspace in their original profiles. Do not convert CMYK to RGB or vice versa. - Do not use CCITT or LZW compression. LZW compression creates multi-strip images, which may show white lines when printed. - Use ZIP encoding for grayscale images. - The gamma of a grayscale image should be between 2.2 and 2.4. - DPI should be between 300 and 600 DPI. Any hints on doing any of this with pdflatex? Most of my screenshots need to be remade, so any suggestions on doing it correctly? I think I saw some wiki pages about this, but a google search didn't help me find them. Also I hve a few charts I need to redraw. Would it be best to generate in a tool that can export in PDF? And then import that in my book? (In a previous book, I used EPS files that I created and exported with inkscape.) Jeremy C. Reed
