Tips
Use the proper program for the proper purpose. Don't use a drawing
program to do page layout, or a page layout program to do imaging
operations such as rotating or silhouetting. Each program is a tool
with a specific purpose in mind. Don't use word processing programs
for final output purposes. Four-color separated film cannot be output
from them (though they work fine for Color Laser Prints). Make sure
color names are consistent throughout your project. PMS 312 will not
output on the same plate as PANTONE 312 CV - the names must match
exactly. The smoothest gradients require about 20 steps per 1/2 inch.
Gradients spanning large areas are prone to banding, especially if
they include light areas of color. PostScript can only reproduce 256
shades of any color from 100% to 0%. Consult on your big projects.
If they are constructed properly from the start many headaches can
be saved later on.
Bitmap files
Files are set up in pixels per inch, which should be 1.5 to 2 times
your final line screen at 100%. For instance, for a picture to output
with a 133 line screen (if you don't know what line screen you would
need please ask), the file should be at least 200 ppi, with 300 recommended.
It is better to have slightly more file information than not enough.
Be sure the files are set up as CMYK, Grayscale or Bitmap. RGB or
Palletted (256K) files will not output properly. PICTs and GIFs should
be avoided, they are not intended for output. Pictures should be rotated
and skewed in the image program, not the page layout program. When
saving a color EPS file, use the WMF Preview for vector files and
JPEG Preview for bitmaps option. It will give you a much higher resolution
image in your page layout file. |
