The road to QGIS 4 is open ! The #QGIS Roadmap for the next major version is now official ! https://blog.qgis.org/2025/04/17/qgis-is-moving-to-qt6-and-launching-qgis-4-0/

The migration to Qt6 is almost complete and will enable QGIS to improve significantly. The #CMYK mode will namely be fully available.

As for releases, QGIS 3.40 LTR will be supported until may 2026. QGIS 4.2 will be the next official LTR in February 2026.

Migration work will be required for plugins, we are working on tools and docs.

I know there are some plugins for @GIMP@floss.social - but what is the reason that @gimp@lemmy.world has in 2025 still no possibility to offer RGB to CMYK options?

I don't understand why some print shops ask for sRGB source documents *without* providing a gamut limiting icc profile so you can see what the hell you are doing.

I get taking in sRGB files for non-vector printing. But without that gamut limiter you're guessing what kind of gamut narrowing will happen so you should still have access to an icc profile.

At least, in my opinion as a self-made expert

Standard interchange image format for Open Source DTP

Hi people,

with all the mayor GUI #DTP software reaching their peak: #GIMP, #Scribus and #Inkscape; and the well established #TeX software #ConTeXt and #SpeedataPublisher, and #ImageMagick we need a serious discussion about which image format we should adopt that works seamlessly across all these applications and it is generally accepted in the press workflow, whereas is embedded or not into a PDF file.

It should be something that has good quality, supports #CMYK and Alpha channels and it is #opensource friendly and perhaps an #openstandard.

I would dare to say that perhaps jpeg2000 matches most of them, it exists from a very long time and can be adopted as common ground, however it is need a combined effort, if what I am writing makes sense for you.

ImageMagick supports it, Gimp 3 currently doesn't, #LuaTeX and #LuaMetaTeX neither. I guess that Inkscape once it will be able to export in CMYK it will decide which format using to store images in CMYK with alpha into a PDF.

It would be very beneficial if we can adopt a format that works everywhere and it is press friendly, thanks.

Testing Gimp 3 Out...

I am testing #Gimp 3 out (#appimage) to see how I can integrate it in my new workflow.

The new #GEGL framework is much better of anything else, but still in rough shape, anyway I am totally impressed, potentially GEGL can do almost anything, now it is just a matter of time (and love ).

Exporting in #JPG, #JXL and #TIFF in #CMYK is feasible although not so intuitive, however #ImageMagick was unable to convert the last two in PDF... I am on #Devuan stable which means #Debian stable, my #ImageMagick version might miss new features.

You can apply GEGL operations on a group and those are inherited by the sub-layers, and this is good and expected.

I had some confusion while exporting in grayscale. The soft proofing wasn't working even though active and the dialog would asked me to save in CMYK which doesn't make sense.

The whole topic about CMYK, besides Gimp itself, looks very confusing to me. I need CMYK because my software, for instance #SpeedataPublisher can't convert from RGB in CMYK. The purpose is because I need to go on offset printing and it is expected to prepare four plates for each colors (Cyan, Magenta, Yellow and Black[Y]); However I could need to go just black and white (grayscale) thus if I have already a grayscale image what is the purpose to export in CMYK? Nothing.

I would recommend to change this line to Press Output and to add more voices such as: Grayscale; CMYK; CMYK + Spot Colors.

What color space profile do you prefer?

Krita supports Gray, sRGB, RGB, HEX, HSL, HSV, XYZ, CMYK, and Lab. In theory, Krita also supports YCrCb. Note that Krita supports unbounded colors as long as the bitdepth is F32.

GIMP's default color profile is a built-in sRGB profile. GIMP 3.0 now supports RGB color spaces beyond the standard sRGB, enabling the handling of images with profiles like Adobe RGB.

Unfortunately, GIMP 3.0 still does not fully support CMYK and LAB color spaces.

It might have taken an ungodly amount of time. But getting these corner cases right in this PDF export is going to mean the world to a lot of people.

Arabic and Hebrew and non messing up the glyphs.

#AskFedi is there a #CMYK parody of #YMCA (the #VillagePeople song)?

eyes bleed in #rgb > eyes bleed in #cmyk

Viva CMYK!
