This is my first email on this mailing list, so welcome everyone and
keep up the good work.
This is the problem: I want to design documents like flyers,
business cards, etcetera. I want to do this with open source tools
under Linux. I want to be able to deliver my files directly to the press
without converting special things or let the press do extra work.
I am very familiar with The GIMP. So I started to make my
business cards. Maybe I made my first mistake here, I don't know yet!
I took a high resolution design because I wanted to use it for more
The business-card has a final size of 55x85mm and has colours to the
edge. So I put 1mm on every side so the total size will be 57x87mm.
I exported my file to Tiff without compression.
I use to ImageMagick tools from there.
convert "Image - Front - RGB.tiff" -colorspace CMYK "Image - Front -
identify -verbose "Image- Front - CMYK.tiff" > "Identify - Front - CMYK.txt"
I converted my file to CMYK and did a check, good color profile. Three
colors white for the background of the Tiff, black and aqua for text and
Now some issues here: Why do they what 300 dpi files? 300 dpi means 300
dots of inkt per inch? So if want a 57x87mm file I must have a
resolution of = ((5.7/2.54)x300)=673 ((8.7/2.54)x300)=1028 == 673x1028
at 300 dpi will result in a image of 57x87mm.
convert "Image - Front - RGB.tiff" -colorspace CMYK -geometry 1028x673
-density 300x300 "Image - Front - Geometry - Density - CMYK.tiff"
identify -verbose "Image - Front - Geometry - Density - CMYK.tiff" >
"Identify - Front - Geometry - Density - CMYK.txt"
Now the resolution and color profile are good. But the Geometry
option does a anti aliasing effect and turns my card in a full > 500
I can correct this by using this command:
convert "Image - Back - RGB.tiff" -colorspace CMYK -sample 1028x673
-density 300x300 "Image - Back - Sample - Density - CMYK.tiff"
identify -verbose "Image - Back - Sample - Density - CMYK.tiff" >
"Identify - Back - Sample - Density - CMYK.txt"
The resulting file I can send to my printer (HP Color LaserJet 8500DN)
But the quality of a 300 dpi image sucks on my printer if I sent the
high resolution converted CMYK file to my printer it looks fine.
Why do they use such low resolutions?
And here I think I made a mistake by using image based text made with
What are the specifications of file's I can send to the press, and how
can I create files according to these specifications?
I send the original RGB TIFF file and all converted TIFF CMYK images to
a press but they could not use them. They went creating new files. And
wanted to know every color and text type and text size of every word.
Now I can pay them. And I still don't know how to create a good file
that I can send to the press.
What am I doing wrong here? Can't I use bitmap based elements in DTP
should I only use vector based elements?
I am feeling totally screwed here, please help me?
