Resolution Question

[jammer_jammer]

<p>I have the job of doing some major editing to a photo that will eventually be used as the back insert on a music CD. I found on line the the correct dimensions are 5.4 x 4.63. So, I dialed those figures into the cropping tool and have cropped the image.<br>

This gives me an image that is 690 x 592 pixels which works out to be a resolution of 128.<br>

I don't do much printing so I have some questions:<br>

1. Is 128 a high enough resolution to print an acceptable image?<br>

2. If not, what resolution should I up-res to?<br>

3. What method should I use? Bicubic smoother?<br>

When answering, please keep in mind that the original image is already a very grainy, black and white so this by no means has to be a pristine print but I WOULD like to do my best with what I was given.</p>

<p>Thanks in advance for any help on this issue.</p>

<p>Are you going to do the printing or is this being sent out to a press? If the former, run off a print and see how it looks. If the latter, call the printer and ask them what resolution they want. They may wish to up-res the image themselves.</p>

<p>Thanks Mike. I will only be delivering the image file. The client will be using the printer/duplicator of his choice. I would prefer to do the upres myself. Given those circumstances, what res should I go up to and what interpolation method should I use.<br>

Thanks again.</p>

<p>for print on press (commercial printing), 300 dpi will be needed.<br>

from 128 to 300, I would do in 2 steps res up (for ex 128 -> 200 then 200 ->300), with correction between steps. You need to convert the image to CYMK and color do color correction too..</p>

<p>good luck</p>

<p>Hi Jammer,<br>

Again, I would suggest getting your client to put you in touch with his printer. Speak with them about their needs/preferences. Many printers prefer to do the up-res and conversion to CYMK (if necessary) themselves. If that is not the case, the printer is still your best source of advice on how much you need to up-res the image. </p>

<p>Mike and Dan,<br>

Thank you very much for your help. This is a B&W so at least I won't have to do that conversion.<br>

Happy Holidays to you both!</p>
