You can use Separate+ for GIMP to convert RGB to CMYK.

Re: [Gimp-user] How to shrink photo, retain quality?? Business card design

[Rick Strong]

Scribus and Inkscape are both good programs, which I have recently 
discovered from Simon Budig on this list.


Do the vector stuff in Inkscape and the pixel stuff in Gimp, then do your 
layouts in Scribus.


Don't forget to convert the RGB image/photo file to CMYK (4 colour) colour 
space for print.
You might try www.rgb2cmyk.org to make that conversion before you place it 
in the Scribus layout.

I haven't tried the service, but it's worth a shot.

Output the photo to CMYK Tiff.

[Gimp-user] Adjust Pressure Sensitivity?

[PlasticTopHat]

Okay, now the pen that came with my Monoprice drawing tablet is acting weird,
with the buttons sticking at times. I have a replacement pen, but I have to
press very hard to get full pressure, and thus full opacity. I tried adjusting
the pressure curve in GIMP both ways, but it didn't seem to help. Isn't that
what that curve is for?

[Gimp-user] How to shrink photo, retain quality?? Business card design

[JoeyF]

Thank you so much for the help-

I tinkered around with what you both recommended and watched some tutorials on
dpi, how to change it and reread what you wrote multiple times. It helped a lot!
I set a dpi of 600 for the entire project by going to Image -> Print Size as
well as making use of Image -> Scale Image.

I have set all the measurements to inches rather than percents and pixels like
Richard recommended.

I haven't had a need to use the plugins yet, but I will definitely keep them in
mind for the future! Thank you for your detailed explanation of how pixels
translate to physical print.

Your replies both answered by question perfectly. I really appreciate that- it
helped a lot!! This taught me a lot more about the program and helped me
understand photo editing more.

Sincerely, 
Joey

Re: [Gimp-user] Adjust Pressure Sensitivity?

[Ross Martinek]

You didn't mention what OS you have, but often this is more a function of the 
OS and the tablet driver, at least on the OS I've used. If you are sure you 
have the most recent driver for your OS, then I don't know what to tell you.

Re: [Gimp-user] Path Tool Annoyances

[akovia]

Just revisiting this to see if it can get a little love.
I don't stroke every path I make, but when I do I am still faced with a
lot of extra work to repair the handles. I've given this a bit more
thought on how to fix this issue and came up with two ways that maybe
can work together.

1. A setting or a keyboard modifier that prevents handles being pulled
out when placing nodes.

2. A threshold slider in the strokes dialog to ignore handles within a
certain margin.

The first option would help prevent problems when creating the path.
The second would overcome previously created paths, or fix problems when
dragging out handles by accident when manipulating the path by the line
instead of by the handles themselves.

Here is a full size example of a render I did. If you zoom in to 100%
and follow the path around, you can see how many problems there are. I
understand it only takes 5-10 mins to go back and fix, but it really is
frustrating.
