resizing - recomended technique

Recommended Posts

Whats the general thought on resizing...

I've got some images that I'm trying to print, and I'm only able to get good copies printed if I don't do any resizing.

I can easily understand why enlarging would be a problem if you enlarge too far, but I'm actually having trouble shrinking.

Whats the best approach - resize in photoshop to the paper size, then leave the printer settings unchanged, or leave the photoshop native and adjust the driver?

Is there a different magic technique?

I'm printing to a Epson 1280, and my shrunken images have a sort of horizontal banding under close inspection. Whats the technique for eliminating this dithering?

Thanks,

_Am

There are several ways to resize digital images in PhotoShop, some can be harmful.

There are times when you'll want to "resample" the image for specific purposes, but for the most part, you only want to change the document size.

Resampling the image, even under the best of conditions will alter it by squeezing the information into a different space. Again, you may want to do this for specific reasons, like making a web graphic that must be 800x600 pixels, or maybe a desktop picture or something like that, but for printing purposes, you'll almost never want to do that.

Here's an example of what happens at the pixel level when you resample. You'll probably have to open these up in PhotoShop and magnify them to really see what I'm talking about.

Notice that when you try to squeeze 8x8 pixels into a 7x7 space, there's a lot of grey that gets created. On a larger image this just looks like mud. Same deal with squeezing 64x64 into 63x63. This time it's a little less noticable, because the reduction in size wasn't quite so great and there are more pixels to play with overall, but you can definately see that some of the pixels turn grey between the whites and the blacks.

Open image in PhotoShop.

Assuming you do NOT want to crop anything other than to -simply- make it an 8x10.

From the PhotoShop menu select Image/Image Size...

DESELECT (uncheck) Resample Image:

In the Width box enter 8 inches
You'll notice the Height changes to 10.784 and the Resolution changes to 173.875.

Press OK.

From the PhotoShop Menu select Image/Canvas Size...

Anchor the lower middle of the image (the part you DON'T want cropped), by selecting the lower middle portion of the tic-tack-toe selection box.

In the Height box enter 10 inches.

Done!

Andy,

I have experienced a similar banding on my epson 2200 and it was when I forgot to select edge smoothing. (just cant' remember if it was horizontal or vertical?)
Using glossy or premium luster paper. etc.

this may or may not fix it.

Also if the printer came with film factory this program lets you easily size the picture to the 4x6 or 8x10 or various sizes and also some minor adjustments. Not nearly as much as photoshop but good for light edits
