Adobe Photoshop is a brilliant package but it is designed solely for photo manipulation and not graphic design. Professional graphic designers when creating a new job will only do their photo work in photoshop and then import it into either Adobe InDesign or Quark Express to create the completed design. It is in either of these two packages that the text, illustrations and photos are put together to create the final PDF which is then printed.
Photoshop is a Raster based peace of software which gets the best result out of photographs. However it is not very good with text. In dead text generally does not look very sharp when printed from a file created in it. On the other hand Adobe InDesign and Quark Express are both Vector based programs, which handle text perfectly. What’s more they are designed to handle imported photos and graphics as well. Indeed if you were to compare a leaflet created entirely in Photoshop with the exact same design created in either InDesign or Quark Express, you would see the difference as soon as they were printed on a press. The Photoshop artwork will not be as sharp.
It is for this reason that all professional graphic designers use at least 3 separate programs to create their work. A photo manipulation program, a graphics package and a layout program.
