  1. Sadly I don't have Affinity Photo, but thank you guys for the great answers! But I have Photoshop - so I was thinking maybe the following process on the exported PNG might even be better because it allows for semi transparency on areas that are not problematic during printing and deletes partially transparent pixels in areas that might cause problems. In Photoshop: 1. Layer > Layer Mask > From transparency. 2. Image > Adjustments > Threshold (128) I have created a !masked! (thanks @R C-R - it seems that I confused the terms "clipped" and "masked") circle, that I exported as PNG24 without any "coverage map" adjustments whatsoever. As you can see there are partially transparent pixels as expected: Putting the PNG24 on different backgrounds shows the partial transparency clearly: Now I did the Photoshop workflow as described above with the original PNG file. The result on the same background is the following: As you can see only the partially transparent pixels that "touched" the background got changed/ removed. The other partially transparent pixels that do not touch the background stay how they are. I think (I am not entirely sure about this but it seems logical) that the partially transparent pixels that do not touch the background are not a problem in textile printing, because they "don't change" when the textile color changes. Please correct me if I am wrong here :p I think this is a reasonable workaround that can be automated for many designs. I am very interested in your opinions on this! Cheers!
  2. @R C-R Could you please explain a bit more on this topic ( I don't have Affinity Photo). So you can check if pixels are transparent or not?
  3. I did some testing after what you said @R C-R. But I don't have Affinity Photo, I am just using Affinity Designer. Remember: Donut 2) Filled Donut Donut 3) Masked donut Donut Donut 4) Clipped donut Using the coverage map workaround and the "nearest neighbor" export, it is possible to achieve no transparency in the export in the clipped donut (donut 4) and filled donut (donut 2): But anti-aliasing is still applied on the masked donut export (donut 3) and the pixels are partially transparent as you can see on the different background colors (I mean the pixels have to be partially transparent, if you can see the background color behind them, right?): If one refrains from using masked shapes and uses the "coverage map" workaround on EVERY object layer while exporting via the nearest neighbor option, the following objects do not get anti-aliased in the PNG export: - Strokes - Filled Shapes - Clipped shapes I still have not found a way to export multiple pictures in the export persona with the "nearest neighbor" option. So far I did that without the export persona via "File --> Export --> Reasample: Nearest Neighbor --> Export". Since I want to export allot of images at the same time, do you know a quick way to do this in the export persona? Cheers!
  4. Ideally there should be no transparency at all ("see through to the background is fine of course - so I want either 100% opacity or 0% opacity). Since anti-aliasing results in transparency or partially transparent pixels, we have a problem there. So your workflow was: File --> Export --> Reasample: Nearest Neighbor --> Export? I did that and you are right, the clipped donut (donut 4) did not have any partially transparent pixels anymore which is great! But the masked donut (donut 3) still has transparency/ partially transparent in it. Nevertheless a step in the right direction Do you think a global anti-aliasing turn-off is a realistic feature for the next update? I already produced hundreds of designs with AD but the lack of this feature will probably push me towards another design-tool. I was just recently made aware that partial transparency can lead to some problems in textile print. This is such a basic feature and the lack of it results in unnecessary workarounds that are time consuming and hard to keep track of. I really don't want to have to apply a specific map coverage setting to every object layer during designing or export in PDF just to import into PhotoLine in order to export without anti-aliasing again.... AD basically alienates t-shirt designers with this situation in my opinion. That is a big market share of potential customers - I simply don't get it and I am getting I bit frustrated as you can probably tell Anyways - thanks for your answer Cheers!

    PNG-24 Export adds transparency

    First of all I like your name, @Medical Officer Bones And thank you for your great answer! Yes I see what you are saying.... I actually created another discussion just this moment: It seems that there are many problems with the "workaround" via the coverage map - I have described this further in the post. Take a look if you want I really don't understand why there is no global option for turning on/ off anti-aliasing yet - I mean this is a big turnoff for some people in regards to using AD and this has been requested in posts years ago. Anyways... Cheers!
  6. This post relates to this discussion in regards to anti-aliasing: Here is why the "workaround" for anti-aliasing removal in exports as shown here does not work for me (or at least I do not know how to make it work...). I use AD for designing t-shirts which I upload in a PNG24 format to several websites. Most print on demand providers don't want any transparency in the uploaded files. Although the workaround via the "Coverage Map" in the "Blend Options" works on simple shapes, it does not seem to work as soon as masking or clipping come into play. I have created 4 donuts (PNG24 export): Donut 1) No anti-aliasing workaround used Donut 2) Anti-aliasing workaround used (no masking or clipping used - just the normal "fill"-option was used) Donut 3) Anti-aliasing workaround used on masked donut Donut 4) Anti-aliasing workaround used on clipped donut (textured clipped mask for "see through effect (layer used to mask with has the same blend options of course) As expected anti-aliasing was implemented on donut 1 after the export. The workaround works great on donut 2 as you can see. But when donut 3 is masked, transparent pixels appear on the export although the workaround was implemented on every object layer. Donut 4 was clipped. As you can see the border of the donut is fine (no anti-aliasing) but the textured mask (which has the same coverage map settings for "no anti-aliasing" of course) appears with transparent borders on the "see through"-parts. Am I doing something wrong? A simple "turn anti-aliasing on and off button" would be such a helpful option in my opinion. Since I create designs with allot of shapes and strokes it is a big pain to have to manually select all object layers and then set the right blend options every time. This would be a great new feature, since this topic seems to be discussed/ requested for years now. Here is the AD file if you want to have a look Anti-Aliasing Demo.afdesign Lookin g forward to your replies y'all Cheers!

    PNG-24 Export adds transparency

    Here is another post on this issue. @R C-R you also participated in it as it seems

    PNG-24 Export adds transparency

    Hey R C-R, sorry for the late response! I am using the "normal" retail version of AD for Mac. I have tried what you proposed and it still did not work somehow. But I did some further research and this seems to be a bigger problem. Anti-Aliasing can not be turned off globally, but there seems to be a workaround. Transparency and anti-aliasing are very closely related. When anti-aliasing gets "used" in the PNG-Exports there will be some transparency in the image by default. That is what I meant in the original post. Cheers, Mark

    PNG-24 Export adds transparency

    I have exported the same design twice (one with "transparant background" checked and one with "transparent background" unchecked) and both PNG-24 exports showed transparency (like in the picture I have attached in my first post) So this sadly did not change the problem... I tried what you have suggested. I set the matte color on white (and on black) and it strangely did not change the export in regards to the transparency - I will try out some other colors but I did not have the time yet. I will keep you updated Nevertheless good info on the PNG-8 and bit part. I did not know that.

    PNG-24 Export adds transparency

    I have the "transparent background" checked/ enabled. When I use the PNG-8 format for exporting the problem gets solved. The anti-aliasing effect does not get applied but the export gets dithered, which I don't want.... Basically I just want to find a way to turn of the anti-aliasing effect The problem is that I work with an "empty" background. I do not have a background color therefor the "Matte" box does not help me
  11. Hey guys, whenever I export in PNG-24 AD turns pixels into transparent pixels although I don't use transparency in AD itself. I have attached a picture of the exported PNG-24 file and the design in AD. I want to export in PNG format without transparency - how is this possible? I hope you guys can help Cheers!
