Date: Tuesday, April 11, 2000 9:07 PM hi, bayard your statement bellow is partially right only for halftoning devices (i cannot believe that the printer resolution doesn't count), like laser printers, but not for continuous-tone printers, like dye sublimation or inkjet. for those, the image resolution must be roughly equal to the printer resolution; so, 300 ppi for 300 dpi printer, 600 ppi for 600 dpi printer, 1200 ppi for 1200 dpi printer, and 1200 ppi for 2400 dpi printer, and so on. of course that for a 300 dpi printer an 250 ppi image will work. so, we may say that, generally: if one wants to use an continous-tone device output, and knows its resolution, the image resolution must be the printer resolution x 1; 300 dpi printer x 1 = 300 ppi image if one wants to print using a halftoning device output, and knows its screen frequency, the image resolution must be the screen frequency x 1.5; 133 lpi x 1.5 = 200 ppi image if one wants to know the minimum halftoning printer resolution recquired for smooth tonal transitions, and already know the image screen frequency, it will be equal to the screen frequency x 16 ---> 100 lpi x 16 = 1600 dpi if one wants to know the maximum screen frequency an image should have for smooth tonal transitions, and already know the halftoning printer resolution, it will be, of course, equal to the printer resolution / 16 ---> 2540 dpi / 16 = 160 lpi = 240 dpi image all the math must consider the target printer and its resolution or screen frequency. and btw, i didn't say that he NEEDED or SHOULD use those numbers, i only took into account a continuous-tone device as the target printer, and used the numbers he wrote for an almost theoric calculation. and for those continuous-tone printers the post at the bottom of this page is not very very wrong. thanks for your complement, bayard.
