Title: Newbie trying to print a good image Post by: zeta forest on March 27, 2013, 12:01:02 AM Hi everyone!
I'm using Ultrafractal I'm breaking my head with a problem I can not solve. I have made some designs that I wanted to print on canvas or sailcloth. When I went to shop to print these images, these have a size 6 cm x 3 cm with a resolution of 300 ppi. Ok! I went home three days ago and since then I am trying to generate an acceptable image to print to a size of 154 cm x 100 cm (or something similar, no matter exactly fit) with a resolution of 300 ppi. And I do not get it! The most that I could do, is an image of 320 cm x 240 cm to 118 ppi. But after many tests I lost the idea of how... So, my question is: How does one set the size and resolution from a ready-made design? To clarify, I'm using UF 5.01, and I'm trying to do this from the render window to disk. Thanks to all Title: Re: Newbie trying to print a good image Post by: makc on March 27, 2013, 02:13:45 AM When I went to shop to print these images, these have a size 6 cm x 3 cm with a resolution of 300 ppi. I must say 300 is a bit overkill for 154 cm, it is meant for 15.4 cm photo prints. You do not need that level of detail in 1.5 meters banner :)Ok!

And I do not get it! The most that I could do, is an image of 320 cm x 240 cm to 118 ppi. But any way, "ppi", or points per inch, is print density - i.e. it is print process property and not a property of digital image you produce. The only real measure of your image is resolution (in pixels). So 320cm at 118 ppi is already 320*118/300 = 126 cm at 300 ppi, and you do not have to do anything special about it.

But the real problem that I can't solve is set the UF render to disk window to works with the values what I set in it.
It change the values for itself after I set the values, changing the results. :hmh: In your opinion what kind of configuration should I do to get a good image definition format in these measures? And a second question is why UF changes the values? Thank you Title: Re: Newbie trying to print a good image Post by: cKleinhuis on March 27, 2013, 08:50:34 AM You need zo increase pixel resolution as makc described
i think the render to disk window has a field for resolution and the layout resolution is not put in there aitomatically in general you can say the bigger the better you may render at something above double print size, and before you go to print downscale it to the exact printing resolution which gives some additiobal cheap anti alias when downscaling Title: Re: Newbie trying to print a good image Post by: makc on March 27, 2013, 11:55:13 AM again, you don't need to do anything :) >> http://www.rocketbanner.com/faq-100dpi.htm << just take your "118 ppi" image, it will print just fine. trust me, I am engineer ;)
