Document Summary

To convert continuous tone data into bitmap data: a (cid:498)good(cid:499) digital image will always . Save as a g)f file: (ave (cid:890) times of the resolution as line screen, line screen is the measure of how many halftone lines are printed in linear inch. The value is expressed as lines per )nch (cid:523)lp)(cid:524). The lower the lp) the more obvious the halftone dots are in the printed image: most all of magazines interiors are printed at (cid:883)(cid:885)(cid:885) lp). Scaling of image = final output size/original size (cid:886)/(cid:890) & (cid:887)/(cid:883)(cid:882), both equal to (cid:883)/(cid:884) The general rule of thumb is to have images with a resolution of (cid:884) times the line screen. eg. (cid:883)(cid:885)(cid:885) lpi requires images at (cid:884)(cid:888)(cid:888)ppi (cid:523)(cid:883)(cid:885)(cid:885) lp) * (cid:884) = (cid:884)(cid:888)(cid:888) pp)(cid:524) Pp) (cid:523)pixels per inch(cid:524: what is true with regards to image sizing, when size increases, resolution decreases, when size decrease, the resolution increases. )mages that are too big can be scale down.
