Don´t discard all layers
Main Topics
Browse All Topicshi all,
I am doing a visual aid in photoshop which is to be printed. Its size is 15/11 inches, CMYK mode and resolution is of 300 dpi(as that is required for printing). Whenever i am trying to save it in a .tiff format, all the colors of the image changes to a different shade of the same color(ex: red changes to a darker shade of red). While saving in .tiff format, in the dialog box that opens, i am selecting these two options - 1) no compression and 2) discard all layers.
But When i am trying to save the same file in .jpeg format, i am not facing any problem. All the colors remain the same. I think .tiff is the right format for printing purpose but then all the colors are changing. Can anyone tell me why this is happening and what is the solution for it.
thnx in advance

Hi Swiftguy,
As Ysageev points, it sounds like a colour profile problem.
Also check that the colour model is set to CMYK if the file is for print purposes. Try flattening the image befor saving As TIFF (you may have some transparent layers that are creating the colour shitf when sving. Keep your original PSD file with all its layers intact (for reference and/or future editing) then flatten and Save As TIFF. It's okay to use LZW compression as this is a lossless algorythm. If your printer gives you the OK you can try sending a JPG but make sure you use minimum compression on that, JPG dumps data to achieve smaller files.
Good Vibes!

hi everybody,
thnx for ur replies.
hi Pantera69, i did give the same settings except that i discarded the layers as it takes up a lot of space if i dont.
hi Ysageev, i actually am not very familiar with ICC profiles, could you please tell me what exactly is ICC profile and where can i check it (or set it ) ?
hi Lobo, the colour model is set to CMYK but LZW compression is not accepted by the printers over here.

You can find some settings for it in the "Sava as" dialog for TIFF.
Also, this is from the photoshop help:
_________
In some cases you may want to convert a document's colors to a different color profile, tag a document with a different color profile without making color conversions, or remove the profile from a document altogether. For example, you may want to prepare the document for a different output destination, or you may want to correct a policy behavior that you no longer want implemented on the document. The Assign Profile and Convert to Profile commands are recommended only for advanced users.
When using the Assign Profile command, you may see a shift in color appearance as color numbers are mapped directly to the new profile space. Convert Profile, however, shifts color numbers before mapping them to the new profile space, in an effort to preserve the original color appearances.
To reassign or discard the profile of a document:
Choose Image > Mode > Assign Profile.
Select one of the following:
Don't Color Manage This Document to remove the profile from a tagged document. Select this option only if you are sure that you want the document to become untagged.
Working color mode: working space to tag the document with the current working space profile.
Profile to reassign a different profile to a tagged document. Choose the desired profile from the menu. Photoshop tags the document with the new profile without converting colors to the profile space. This may dramatically change the appearance of the colors as displayed on your monitor.
To preview the effects of the new profile assignment in the document, select Preview.
To convert colors in a document to another profile:
Choose Image > Mode > Convert to Profile.
Under Destination Space, choose the color profile to which you want to convert the document's colors. The document will be converted to and tagged with this new profile.
Under Conversion Options, specify a color management engine, a rendering intent, and black point and dither options. (See Customizing advanced color management settings.)
To flatten all layers of the document onto a single layer upon conversion, select Flatten Image.
To preview the effects of the conversion in the document, select Preview. This preview becomes more accurate if you select Flatten Image.

Hi swiftguy,
That´s strange !!!
I just tried to save a JPG as a TIFF file and there wasn´t any alteration in the colour.
When you save you get these options:
Image Compression - should be NONE
Byte order - IBM PC
DON´T save image as pyramid
Layer Compression - should be RLE
you could also save it as a JPG ( maximum quality )....it´s ok for printing !!!
good luck
