Printing
Q1:

Which is best for printing to my inkjet: RGB or CMYK?

A1:

Your best bet is simply to try it and see. Although most inkjets use CMYK inks and may recommend using CMYK mode for printing, most people have found that they are happier with the results when printing in RGB. (Most non-Postscript printers will convert to RGB mode before printing anyway.)

Q2:

How do I determine the correct resolution for my laser printer?

A2:

In general, there is no "easy" formula for determining the maximum resolution required for your printer (most formulas are for commercial printers, not digital devices). Although it takes a bit of time up front, I suggest doing a test. Scan an image at multiple resolutions : 75, 100, 125, 150, etc., up to 300 ppi. Just scan a small portion of an image. Put all these images on the same page in the page-layout software of your choice and then print the page. When you compare the quality, you should see that 100 ppi is better than 75 ppi, 125 ppi is better than 100 ppi, etc. However, you will eventually see a clear degradation point, where higher resolution does not improve quality. It may be quite low such as 125 ppi or 150 ppi. Additional resolution will only add printing time, not improve quality. Every printer is different, so you may want to save the page to test other printers as well. (Just as an aside, this concept applies to photos or any other continuous-tone image.)

Q3:

How can I get rid of banding on gradients? When I print images that have a gradient in them, sometimes there are obvious bands of color . How can I avoid that?

A3:

Under the Filter menu select Noise>Add Noise. Then enter 24% for the Amount and select Monochromatic as your settings.

Q4:

How do I print at a high resolution? I own a printer that's capable of 1200x1200 resolution printing, but I can't get images in Photoshop to print above 600 dpi. I am unable to select a resolution higher than 600 dpi in the Print dialog. I am using the most updated printer driver available to me.

A4:

Several things come to mind: First, the printing resolution is determined by the actual resolution of the Photoshop document, not by what it says in the Print dialog. So it really doesn't matter if you can only pick 600 dpi in the Print dialog; it is the resolution of the document itself that matters. More importantly, with the exception of line art, you don't need that high of a resolution for most scanned images. Typically, resolutions of 150250 ppi are sufficient for laser printers, including ones that are capable of 1200 dpi. Try creating several copies of a photo at different resolutions100, 125, 150 etc., up to 300 ppi. Then print them all and compare the quality. You will notice a point at which higher resolution does not improve the quality. Use that resolution for all your scans .

Q5:

Is there a quick way to see at what size my image will print? I'm often confused by the size of the image on my monitor compared to how big it will print. Is there a quick way to preview the print size ?

A5:

Go to File>Print with Preview to see the orientation of your image on the page. You can also access a variety of options that will determine the position of the image on the page. Try tweaking the settings for Position (Top, Left) and Scaled Print Size (Scale, Height, Width, and the Scale to Fit Media checkbox).

Q6:

How do I stop an image from centering when I print? Whenever I print an image, it always centers on the page. Is there a way to change that?

A6:

From the File menu choose Print with Preview and in that dialog uncheck the Center Image checkbox. Adjust the Position of the image using the Top and Left fields. Note: If you select the Scale to Fit Media checkbox, Photoshop will automatically select (and gray out) the Center Image checkbox.

Q7:

How do I add crop marks to my print? I wanted to print a small image to my laser printer and have crop marks, but I wasn't sure of the best way to do that. Can you help?

A7:

From the File menu, choose Print with Preview. Select Output from the drop-down menu below the preview and check the options you want (namely Corner Crop Marks and Center Crop Marks).

Q8:

What is meant by "some clipping will occur" when printing? When I tried to print my image, I got a message that said "some clipping will occur." What does that mean, and how do I get around it?

A8:

That message also says "the image is larger than the paper's printable area." That tells you that the image is larger than the size of your paper. First, check to make sure that the Page Setup (under the File Menu) is appropriate for the size of your image. Changing the Orientation from Portrait to Landscape may better fit the image to the paper. If that still doesn't help, go to File>Print with Preview and click in the Scale to Fit Media checkbox. Now, your image will be scaled to fit the paper. Note: If you choose Proceed when you get this message, the image will still print, but parts of the image will be cut off.
