Lines will not print !?

[mac_mceldon@adobeforums.com]

Hi,

I've got a design that has fine 0.25 lines in it. When exported to pdf these lines will not print to paper.

However doing a test and creating a new document with lines down to 0.25 - this prints no problem ?

Any ideas ?

Thanks,

mac

Print on what? It's entirely possible that the printer simply can't
handle a line that thin.

What do you mean "doing a test", how exactly are you testing? You mean you print to PDF and zoom in to see if the lines came out in the PDF (electronic) output?

thin.





What Robert says is very true. I tried printing fine lines a few years ago on a Xerox machine that was not able to handle that. I tried printing it to another printer, but this time it was on a Xerox COLOR Machine and the lines appeared perfect.

If you don't have another machine to print to, you are going to need to increase the stroke on those lines a little bit to make them appear on paper.

Mac,

as a rule of thumb: the thinnest printable line width
is 1/Lpi. Not much less. For 100 Lpi: 1/100 inch=0.254 mm .
If you mean 0.25 pt then it´s hardly printable.

Many people think that the thinnest line is defined by
printer dpi. But a line can have a color and it can be
gray instead of black - a line has to be rastered.

Can be tested by printer resolution test patterns (400kB):

As already said: the printers behave a little different.
Some PostScript printers replace zero line width (which is
allowed) by the thinnest visible line.
