Hi folks I need to send one of my 3D drawings to anyone in order to print. But I have a problem. I usually save my Poser files in default jpg (72 ppp) but he is requesting me a print quality (psd 300 ppp). I can't draw it again. And of course if I change the resolution from 72 to 300 ppp, the pic has an important lack of quality. There is any process to filter or refine the pic the most possible?

do you have the original in photoshop format? if not, you might try a trick that often works for me. save it in photoshop format, then, making sure it now IN that format, go ahead and resize image to 300 making sure that the resample is set to bicubic... you can change the JPEG to the same when you "package" it. this doesn't always work for me... nine out of ten, but when it does, it can be a lifesaver.

Thanks. I'll try it :)

Thanks, I hope it works for you. Lou.

Okay. (I'm using the shorthand "ppi" to mean pixels per inch in what follows) Resolution is only meaningful when you express the pixel dimensions of an image with respect to an intended physical size. So, if I have an image which is 300 pixels square, then if printed at resolution of 300 ppi it will measure 1 inch along each side once printed, but the same image printed at 150 ppi it would measure 2 inches. The image has not changed of course, but the ratio of pixels to inch has and /that/ is the resolution. Upsampling from 72 to 300 ppi for the same expected print size will not produce a good quality image. Not even Photoshop can fix that. I'm not sure about the "I can't draw it again" bit. Why not just re-render at higher pixel dimensions? (Assuming this is an image sourced from Poser). I've probably misunderstood this :(

Hi lunqvist... I think there is a misunderstanding... if you go to the TOP of image size, you ARE changing the actual size of the image, but the option in the lower section, that is pixel density.... took me a few to realise that, back in the stone age. what I recommended was a re-sample.... like I said, SOMETIMES it does work. Lou.

Yeah, an 800x600 image is exactly the same size at 10ppi and 1,200ppi - it's STILL 800x600 pixels when all is said and done. There's absolutely NO chage in quality or size when you just change the resolution, and upsizing the actual document above 10% (in Photoshop alone) will start giving you unwanted artifacts. You might want to invest in something like Genuine Fractals - oddly, there's an article on the fronts page of this website about it - great program, and if you're going to be preparing it for commercial printing you'll need to convert it to CMYK (or the guy requesting the file might do it for you when he gets it - but they tend to ask for it already done). Good luck and congrats on what sounds like a sale! -Lew ;-)
