bad quality prints [white dots in text]
« on: March 24, 2014, 03:26:20 pm »
Hi everyone !

Im new to Scribus but Im impressed with this program. Its really easy to use. But I cant get good prints from Scribus or PDF generated files.
I have watched and read many tutorials and posts on this forum and cant solve the problem.

After printing from Scribus or PDF generated file I have all of the text coverd in very small black dots. I tried different PDF formats, different quality options and more and still cant figure it out !

Scribus file and PDF attached.

Please help :)

hi piotr

your .pdf file has a light red background color (#FEFAF3). when i export a .pdf from your .sla, the background is white (#FFFFFF).
i assume, the black dots are caused by your printer trying to print this background…

When I go to File->document settings->Display->Colors I have the color white as default. Where can I change background color ?

hi piotr

i couldn't find any background color in your .sla file.
how did you generate the .pdf file? (a new export to .pdf might solve the problem – at least my .pdf from your working file doesn't show this background color…)

I export PDF using export function in Scribus, my esport setting are attached (the program Im using is in polish). I tried printing on OKI and HP Laserjet printers and I`ve got the same results. :(

EDIT: when I print directly from Scribus I get those dots in text as well

hi piotr

i don't really uaderstand the difference between your way to generate the .pdf file and mine.
but why did you exclude the background layer from the export? (there aren't any objects on it.)
the background layer is a solid white plane. when you export your file without it, every free space between your objects will be transparent.
if you don't need this transparency, try to include both layers while exporting – it might solve the problem.
on my system (macOS 10.9.2, scribus 1.4.3) even the transparent .pdf file doesn't show this light colored background, but sometimes it's worth trying without understanding the whole thing…

Tried with the backgroung layer turned on for printing and still the same results. Tried even printing a new document from default template from Scribus with some graphics - everything covered in white dots. It cant be a problem with my laptop or printer becouse I already tried on different computers and printers. I even switched to a Linux version of Scribus nad I have the same thing.

I think the problem is simple but it affects Scribus as a whole. I will try to reinstall the program.

Try turn off color management.
In Your pdf file there are objects tagged as sRGB icc profile. (it is only for monitor profile) Perhaps it is problem beetwen printer, icc profile and file.
PDF-X3 holds icc profile.

Im currently at work but when I get back home I start experimenting again. Maybe with luck this time :)

I tried switching colour management on and off with no luck...

EDIT: I made a scan to show what the problem is.

You are exporting PDF/X-3, what do you use for printing it? Anything else than Adobe Reader could probably have problems handling it.

And is there a particular reason you use PDF/X-3? Have you tried a plain PDF 1.4 or even PDF 1.6?

I have tried all of the PDF formats avaible in Scribus, PDF/X-3 was used in latest attempts. And I have the latest Adobe Reader for reading files and printing :)

It is been a while since I last used Scribus but yesterday I had another chance to make a new project in it. So using default settings I made a simple project for a hospital. Using PDF 5 export option I still have those small white dots everywhere in the text. But I noticed that they are smaller when I adjust the  resulution from 300 DPI to 600 DPI. But they are still there  :(

So problem is unsolved and my frustration is getting bigger :(

PS. Project and PDF file attached.

Now something is wrong here. When you export to PDF from Scribus any text will be exported using fonts. The text will NOT be affected by any DPI setting, DPI settings will only affect bitmap images.

I know that it is strange and should not be happening. Utnik suggested some time ago that I have a background colour that could affect PDF files but I can`t find any.
