Scanning Transparency Question

Postby KLS Images » Sun May 11, 2003 2:59 pm

Sorry if this is old hat to you, but scanning transparencies is a new avenue for me.

I am scanning a transparency that a client provided. It is on Kodak film and has what I would call a color patch test control strip on one side with a gray scale on the other.

Am I correct, that if I place my cursor over the color patches after scanning in PhotoShop and look at the Info tab, I should read these colors as CMYK. For example, if I place the cursor over the Red patch, it "should" read the same as the PhotoShop CMYK swatch of 0, 100, 72, 0?

Or, in other words, if I were to create a square and fill it with the PhotoShop CMYK Red swatch, the control strip on the trans, and the square I made should look the same and read the same value.

Is this correct?

TIA
Ken

Dear Ken, the densitometer data (that you read in the information of your Photoshop) refers to whatever the source is.
If you scanned that transparency with SilverFast as "RGBscan", the data is RGB values; unless you changed the image mode in Photoshop from RGB to CMYK.

If, however, you scanned that transparency as "CMYKscan" the values should refer to CMYK values (althoug the actual data on your screen remains RGB data).
