KPD seems to prefer RGB documents. Not an expert, YouTube is full of tutorials.
E.g.
-
So which black do you need? Please use CMYK color sliders, and no other like color wheel.
default swatch gives cmyk 0 0 0 100, but this will look dark brownish on display to simulate how it will look on paper
you may want rich black, then add other colors, e.g. 100 100 100 100, but that will normally exceed max tint limits of printers.
ask your printer what they expect.

Found older post, does it help?

Can you upload a test file showing the issue?
-
Which document color format and profile do you use?
-
When working with wide gamut color profiles it is important to use RGB/16 instead of RGB/8. otherwise you have a high risk of banding effects in areas with smooth gradients.
So a agree to the advise, export to RGB/8 and a smaller gamut as last step. Keep all edits in RGB/16 and any suitable wide color format.
Also note AdobeRGB and other wide gamut formats do not contain (fully overlap) each other. Depending which colors are actually used in the document, and the intended output (print, lcd display) you may need switch earlier to AdobeRGB (still RGB/16). After exporting, check the exported files for issues like clipped tones or banding.

This shows exactly what I want … now I have to understand how you did it. LOL. Is there a difference between the Gradient Tool and the Transparency Tool for this context?
You can use both, it has some minor differences in the steps.
Transparency tool:
- create 1 rectagle, make solid fill
- duplicate it 3 times
- use original as center piece
-
use first copy as edge piece.
- use transparence tool to create gradient transparence at one edge OR use gradient fill, add a node near edge, select edge node, reduce color transparency to 0%
- duplicate 1 time, and rotate by 90°. duplicate 2 times more
- move edge pieces to their position
-
use 2nd copy as corner piece
- use transparence tool to create radial transparence at one corner OR use gradient fill set to radial, add a node near edge, select edge node, reduce color transparency to 0%
- duplicate 1 time, and rotate by 90°. duplicate 2 times more
- move corner pieces to their position
- Now use move tool / constraints panel to set the correct parameters for every node. (I did not try to do this before duplicating)

If it only worked consistently on all platforms.
This was a major set-back for me when switching from PC to Mac that it is not available in many places like PT filter.i really like it where available
-
Very strange. I tested in latest beta and it worked there. But I entered formula from scratch, only copied image layer, not the PT layer. Will redo testing.

have build 2256, which I suppose is the latest? Nothing on the Windows side, either, rgbtoi still works, but no value boxes for sliders.

Which Mac (CPU) do you have? Some of the PT filter issues affected M1 (and maybe later) models specifically.
then i see you are using different formulas than the OP.

It displays the weighted grayscale of the image (using approximately 30% Red, 59% Green, 11% Blue for the conversion to grayscale).
rgbtoi uses different factors,
https://en.wikipedia.org/wiki/Grayscale
The sRGB color space is defined in terms of the CIE 1931 linear luminance Ylinear, which is given by[6]

its a bug already fixed in 2.4 beta. PT filter was broken in multiple aspects in 2.3.1 on Mac.

and hold cmd on macOS (ctrl on Windows) to switch to the Node Tool;
The questions was asked in the iPad section, and often no hardware keyboard is available. I find it easier to switch tools instead of fiddling with command button. But it works as described by MEB on iPad.

Just to add another overly complicated workaround:
I made a rectangle parted into 9 sub-tiles, using constraints, and specific gradients (linear for edges, circular for corners, solid for center).
It can be scaled to any size, the feathered edge keeps it width. In case you want to change the width of the edge, simply mark 3 of the tiles, and adjust height/width accordingly, repeat 4 times, and adjust center box last.
To change color, either change all 9 manually, or add a rectangle in intended color and nest the symbol into masking position.

No luck - not available on iPad.

If you use lens correction (which most people want), specifically barrel distortion correction, there is no longer any 1:1 relation between RAW sensor pixel (x and y amount) and resulting pixel amount, as transparent areas are normally cut off.
I have no actual evidence, but I assume most RAW converter will actually scale the image to the „advertised“ pixel size to preserve the field of view.
To find out, we can try to compare out of camera jpg with RAW files with lens correction activated / not activated in Affinity (new stack)

While editing I have noticed there are times when the screen does not refresh to show the latest change to the work. For example I am working on a text right now in Designer and made it a compound so I can add strokes to the text.
While some people blame driver versions and other factors, those issue plagued me on all platforms (Windows, Mac, iPad) and a multitude of OS Versions and CPU/GPU vendors, and even when using WARP renderer which is fully Affinity software and not relying on anything else. It is far more probable unfixed bugs or fundamental design bugs in Affinity apps. In many cases, changing the zoom factor triggers a redraw.
If possible use navigator panel and enlarge it. If you see any rendering discrepancies between canvas and navigator panel preview you know it is a Affinity bug. If both show same content the likelihood is on GPU driver issue.
Always compare WARP driver (e.g. by having a beta installed in parallel) to openin& the same file in Retail version with HW accel active.

When I use Metal on Mac mini, rendering is completely broken. The results above are from Beta with "OpenGL rendering" in Performance settings.

Hi,
I made a PT filter to generate the Mandelbrot set. It works in RGB16.
After converting to RGB/32 and slightly adjusting the formula to "unbound" color values (becoming larger than 1.0), strange thinks occur:
Whe I duplicate the PT filter layer multiple times, the alpha channels becomes 0 after 9th copy, despite alpha channels is never changed in the PT filters (except the base PT filter which creates "1" for all pixels.
I assume an overflow situation.
Depending on EDR active or not in 32-bit-preview panel, the transparent areas are shown with checkered board, or black which is another bug on its own.
Happens with 2.3 (latest retail) and 2.4 beta (2.4.0 2256)
Image 1: 8 copies of PT filter, all well
Image 2: 9th copy leads to transparent areas (checkered board visible)

Please add option to show length/rotation for any vector layer object, in addition to x/y size.
for curves of exactly 2 nodes, it is very easy and partially already available in some apps, but nut in all Photo/Designer and all platforms Dekstop/iPad.
in general, for any curve with any number of nodes, affinity shows the x and y size.
just use the middle y and min/max x position as default nodes in case more then 2 nodes exists. -
Hi,
often I need to fine-tune layer position by moving with mouse and some snapping options. As position can be relative to other layers, i might need to start zoomed out.
for small objects it is difficult to grab the layers in the correct point, meaning not touching any of the resizing nodes.
it would really help if move tool/ transform panels adds lock buttons:
- lock object size. You can adjust x/y position or rotation about selected anchor point, but cannot resize object even if you grab an edge node by mistake
- Lock object position. You can adjust object size or shear/skew angle, but position is fixed to either:
- the selected anchor point
- the shape center point (which might be manually repositioned)
handling of rotation and skew might need to get separate lock buttons.

Probably you need to rasterize the image layer. Then it will work.
