Pinkpanda Posted January 6, 2022 Share Posted January 6, 2022 Hi, I keep coming across an issue when trying to print some designs I’ve created. When I print, sometimes it prints out a line or 2 that seems to be like a frame around a piece of clip art or text, but the line is not in the design and does not appear on the screen. Does anyone else have this problem? Quote Link to comment Share on other sites More sharing options...
NotMyFault Posted January 6, 2022 Share Posted January 6, 2022 possibly an issue with partial transparency. Try to add a pixel layer, fill it with pure white, and place it at the bottom of the layer stack. Another option, only for testing: Add a channels mixer on top. go through all channels: red channel: red set to 0 alpha set to 100% green channel: green set to 0 alpha set to 100% blue channel: blue set to 0 alpha set to 100% alpha channel: bias set to 100% The resulting image must be 100% white. If there is the slightest non-white pixel, this can cause issue when printing.

Staff Dan C Posted January 12, 2022 Staff Share Posted January 12, 2022 Hi @Pinkpanda, Sorry to hear you're having trouble! Can you please confirm for me, did the above suggestion help resolve this issue for you? If you're still having trouble when printing, are you able to provide a copy of your Affinity document for me? Many thanks in advance Quote Please Note: I am now out of the office until Tuesday 2nd April on annual leave. If you require urgent assistance, please create a new thread and a member of our team will be sure to assist asap. Many thanks Link to comment Share on other sites More sharing options...
PixelDude Raoul Posted May 6, 2022 Share Posted May 6, 2022 De bijgevoegde foto is samengesteld uit een foto met kaarten en een aardappel. De aardappel zit op een laag met transparante ondergrond. Wanneer ik die aardappel met transparante ondergrond op de kaartenfoto 'plaats' dan zitten er lijnen rond. Ik heb verschillende 'exports' geprobeerd.pdf - geen lijnen png, jepg, tiff, - lijnen Quote A nice picture doesn't have to be a 'technical good' one, but 'different' from all other ones.

NotMyFault Posted May 6, 2022 Share Posted May 6, 2022 Could you upload the actual file? I assume the embedded .afphoto file is causing the issue, to avoid, export the potato as png (or any other format supporting alpha channel), and use the png file.

PixelDude Raoul Posted May 6, 2022 Share Posted May 6, 2022 Hierbij het AP bestand. De lijnen zijn niet bij alle vergrotingen zichtbaar, je zal moeten inzoemen. Bij export zijn ze altijd zichtbaar (behalve als pdf). _X044925-met aardappel.afphoto Quote A nice picture doesn't have to be a 'technical good' one, but 'different' from all other ones.

NotMyFault Posted May 6, 2022 Share Posted May 6, 2022 Unfortunately the file is RGB/32, and contains only one flattened layer. To analyze, we would need the file in the version from your screenshots, still having separate layers. To save space, you could resize to a lower redolution.

PixelDude Raoul Posted May 7, 2022 Share Posted May 7, 2022 Ik heb die (per ongeluk?) verwijderd. Ik zal eerst de AP terug opbouwen. Verwijderd ... vreemd genoeg. Enkele weken reageert het programma vaak niet en moet afgebroken worden. Een probleem dat ik voorheen niet kende. Maar dat is een andere kwestie. Wanneer ik de tijd vind bouw ik een gelijkaardige foto op. Quote A nice picture doesn't have to be a 'technical good' one, but 'different' from all other ones.

PixelDude Raoul Posted May 7, 2022 Share Posted May 7, 2022 Ik heb de nieuwe opbouw eenvoudig gehouden door enkel centraal met 'place' een aardappel over de schoppen te plaatsen. Bij sommige vergrotingen zie je de lijnen verschijnen en ook de export naar een jepg vertoont de lijnen. 649795296__X044925met1aardappel-test.afphoto Quote A nice picture doesn't have to be a 'technical good' one, but 'different' from all other ones.

NotMyFault Posted May 7, 2022 Share Posted May 7, 2022 Its seems Affinity is unavoidably causing this 1px wide line at the outer edge of the image, if it is scaled in size. There are numeruous related threads. If you scale an embedded image using non-integer multiples, the edge pixels are treated wrong. I reported this before, but Affinity did rate this as “feature request” To avoid, use one of these techniques: add a rectangular shape as vector mask to the embedded image layer, covering the “wanted” area, but leaving the edges. don’t use embedded images. Instead use exported images (PNG format to preserve alpha), as these cover only the used area.

NotMyFault Posted May 7, 2022 Share Posted May 7, 2022 Please find a much smaller simplified file to show the issue. The parent file contains 2 copies of the embedded file: native size 100x100 stretched to non-integer size the 2nd file causes 1px darker pixels at the edge. This is probably caused by fractional edge pixels getting anti-aliased with black (RGB 0) pixels outside its canvas. embedded seam bug.afphoto Quote Mac mini M1 A2348 | Windows 10 - AMD Ryzen 9 5900x - 32 GB RAM - Nvidia GTX 1080 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 iPad Air Gen 5 (2022) A2589 Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.

PixelDude Raoul Posted May 7, 2022 Share Posted May 7, 2022 Dat zal ik in de toekomst in gedachtenhouden. Voor mijn foto had ik het met 'inpainting' opgelost. Bedankt.
