I think a test comparing PPI would be quite helpful. Personally I can see a difference up to about 450ppi on my Pro-1000 (printed on highest). So printing at 300ppi makes crisp diagonal edges look jagged (slightly pixelated) so instead I print at 600dpi.
Learn what the native DPO is for the printer and create the print at whatever size you want at that DPI. For example, Epson's are usually 360 DPI. So if I want to make a 24x36" print, I make sure that I resize the image to 24x36" at 360 DPI. You do this because the printer is going to it for you anyway. So, if you send a 180 DPI image to the printer, the printer driver will upscale it to 360 DPI using whatever mysterious, unpredictable algorithm it uses. So, I upscale myself (trying many different approaches) so that I can send the best possible image to the printer and I'll know exactly what the printer will print.
I print at the native DPI, but generally at 200 PPI both on a pro 1000 and an Epson 7500. It works pretty well, and although some of these images go to private customers, most of what I do is for exhibitions. You can go as low as 182 without appreciating a difference. This is not minor as it affects cost, but also sizes depending on the resolution of the camera used. You can increase the size of a 24 MP image either through Lightroom or Topaz, but artifacts appear with both. A 47 MP will give you naturally an A1 and a 100 or 150 delivers an A0, but many photographs are produced at lower resolutions.
Thanks for the video Tim, very informative. I watched another video from Keith Cooper who was suggesting that it could be argued that going as low as 150 DPI for the larger prints can be acceptable, when viewed at a “normal” viewing distance. If correct then that, as I understand it, could be approximately 50% savings on ink. What is your views on this?
Hi Keith, yes i agree that going down to 150ppi on a large print can be ok. It all depends on your viewing distance when you get up close you will see the pixels. I have had a look and it seems the lowest DPI setting on the Canon is 1200dpi and on the Epson's 720dpi seems to be the lowest. You will save a little ink using the lower setting and viewing distance comes into play. I would normally say to use 300ppi or 360ppi on prints up to A0. Tim

Hi, thanks for the videos. I've got a question regarding papers, I don't know if this is the best place to ask. I have just purchased a second hand Canon 10S, which came with an assortment of Fotospeed papers. It's a long time since I've done any photo printing and previously I have only used glossy or lustre papers. I have printed out a few prints on the PF Lustre 275, and am very happy with them. There were also some art papers, and I tried printing on Platinum Etching 285, which I'm not so keen on. The prints are looking quite dull and certainly no where near as accurate to the on screen representation I am getting with the lustre paper. I have tried in Affinity photo, and also using the Canon Print Studio Pro, via DPP. I have soft proofed in both applications using the ICC profile you provide (I have checked I'm using the correct one). Having never used art papers before I am not sure if that's just to be expected or I'm doing something wrong. I have spent the day researching on the internet and not really been able to work it out. Any hints or tips you can provide would be greatly appreciated. Thank You
@@orkneyed6528 Thanks, not actually that silly as I've not used art paper before. I printed on what I thought was the textured side, but now I look carefully I can see both sides are textured. I'd never heard of the finger test, but just tried it and yes I did print on the wrong side 🙄
Hi Snorri, as I understand it the paper goes through the printer slower making the dots of ink closer together and appears smoother. It needs to put more ink down to cover the same area on the print. I hope i've explained that correctly, Tim

They're exactly the same because they use the same amount of ink.
Very informative. Thank you Tim.

Hi Alex, I think this is next on my list to test out the PPI settings. Tim

Hello Tim, Silly sort of question but would the DPI also effect the longevity of the print? Keep well, keep safe and find time for some fun.
Hi John, it shouldn't effect it as the lower DPI will be have the same archival-ness. I will look into it though. Tim

Sorry if this sounds silly but make sure your printing on the right side of the paper. Doe the wet finger test.
@@orkneyed6528 Thanks, not actually that silly as I've not used art paper before. I printed on what I thought was the textured side, but now I look carefully I can see both sides are textured. I'd never heard of the finger test, but just tried it and yes I did print on the wrong side 🙄
Oh boy do I feel silly. It looks so much better when you print on the correct side. Thanks for your help.
More dpi uses more ink???
i.e 1200 dpi uses more ink than 300 dpi????
How can you use more ink on an inch with more dots if you cover the whole surface of an inch or square inch in both cases ?
Hi Snorri, as I understand it the paper goes through the printer slower making the dots of ink closer together and appears smoother. It needs to put more ink down to cover the same area on the print. I hope i've explained that correctly, Tim
Really interesting video, but... pixels, not pixals. Picture Elements. ;)
That'll be my South west-ness coming through, Tim
