Enlarging jpg Images WITHOUT Losing Clarity?

Hi Guys

I have a stack of jpg image files that look great great. I want to enlarge them so they still look good! I know the usual result is horrible blocky/fuzzy edges.

These pictures are destined for T-Shirts so the images don't need to be of photo quality.

Is there any software that is designed for this purpose?

John,

I use photozoom pro after a recommendation on here. Seem to recall about £100.

Not perfect but does a very good job.

You can also check out Genuine Fractals - tested that a long time ago and was pretty good.

Hope helps

John, sometimes you can get away with just increasing the resolution in a photo program, especially when they aren't going to be blown up that much, can you post a sample image, maybe you will get some examples of what can be done.

alien skin do a plug in called Blow up


BlowUp offers the highest quality image resizing available, better than bicubic interpolation and any other third party solution. BlowUp makes advanced image scaling easy, preserves smooth, crisp edges and lines, and creates four times (1600% area) enlargements from any image without jagged artifacts or halos. In some cases, BlowUp can enlarge up to six times (3600% area) without obvious artifacts

Amazing what copy and paste can do John.
If you look at the text you can tell it did not write it as the spelling is correct and has punctuation in the correct places.

I use photozoom pro as well. Excellent for doing really big stuff. Corel Photopaint X3 is good enough to enlarge most Images for printing to shirts and stuff though.

I tried photozoompro myself a couple of months ago. Then I tried to email the increased res. file to my outsourced large format printing co. in England.........no way, hose.

If you have in house printers all well and good but any clues as to what to do if you havent?

Gareth - if you have photoshop, you could try the "save for web". This gives you a preview as to what the finished version would look like saved at a lower level (guess more compression) - you can normally dramatically reduce file size this way. If all else fails, burn larger file to disk and post to your wide format printers - will only take extra day (although can be a pain if done too often).

Some printers if not all should be able to enlarge image for you. Some may charge for this others might not. I have sent disks before in the post only drawback is it takes a day or so longer than e-mailing. I prefer to do any scaling myself but that's cos I'm a control freak

I find just resampling using the photoshops bicubic smoother does a good enough job, obviously it can only blow up so much but seeing as you only want to blow up to go on tshirts Im sure that should do the job if its not ridiculously small.

If you are going to use photoshop increase the image 5% at a time. It reduces the distortion compared to trying to increase it by 100% in one go.

We use photozoom pro here though.

Although we did a banner the other day 5m by 5m and scanned it in from a negative.

Done something similar in Corel Photopaint. Taken a small image and changed the dpi setting first, then altered the size in mm to what was required. It does help with enlarging, but can make the image a little fuzzy, as if it has a soft focus.

You could even print them out in hi-res and re-scan at a high dpi, problem solved.
