------- Additional comments from ap...@openoffice.org Sat Jun 13 16:27:30 +0000 2009 ------- Sometimes in the printing of art, you want to control the screen frequency/lines per inch(LPI) of fill areas on the output device, especially if your art is being reproduced on a printing press. If the fill area is 50% black, the dots of the screen cover 50% of the paper. The LPI specifies the spacing of the dots. The lower the LPI, the larger the dots. Their are various types of printing processes, three of which I am familiar are Offset, Letterpress and Flexographic. Controlling the LPI of the area fills is important in matching the capabilities of the reproduction equipment. If you order your printing plates from commercial plate maker, you tell them the LPI to use on your plate. Some vector art programs, like CorelDraw, allow setting the LPI, under postscript settings, for individual objects on the same page or the default LPI and overrides the default of the output device. This is useful for graphic effect or matching the capabilities of the reproduction equipment. If your produce your own plates via laser printer on polyester plates, you need to be able to control at least the default LPI for screening fill areas. This function is not available in the output drivers of any typical laser printers that I have encountered. I use CorelDraw because it has LPI control for postscript output devices. I have not seen this control for other than postscript devices, probably due to the heavy use of postscript in the printing industry. I am proposing, that if any developer understands how this can be done, that this feature be added to DRAW for individual objects and the print dialog box for the default setting for at least postscript devices. I think this would expand the usefulness of OpenOffice.org for the printing industry and various graphic effects by the artist. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
