I did some significant retouching of some line-art scans in Photoshop before realizing that the resulting file sizes are way too large (like 50MB)...I'm no scanning at an appropriate/lower resolution. Having done the line retouching, is there a BEST way to reduce the file size which will result in minimal distortion/pixelization of the line art? I suspect there are several ways to go about it (such as a proportional file size reduction command), but I'm wondering if there are different ways and which is cleanest. Thanks So Much, pdog

Reducing image size is usually no problem, You'll lose some of the detail so you might want to use the sharpen filter first, then go to Image/Image Size and have at it. - Ken Heronheart -

lineart is solid black and white work, meaning that if you were to save the file as a .tif format file with lzw compression (100% lossless compression btw, ingenious stuff),` expect your file size to drop to a few megs at most. One of my old works, The Grudge, was a 550+ meg photoshop file (this included all the layer information, but it really was a massive file) and it shrunk to about 40 megs with tif and lzw. A more recent thing of mine, Val and AI (in the 2D forum) is a 30 meg or so tif file without lzw (Expresion doesn't give the option for LZW compression when exporting). Reopen in photoshop and resave with lzw, and the same file is now a paltry 1.89 megs. for info on what LZW actually is, I've gone over it a few times in photoshop and 2D Graphics forums i believe, just do a search.
