Placing Images In Illustrator Are Blurry.

Hello I have this problem in CS5 that any type of image or line art are always blurry. All my work is for print and perhaps just the preview is blurry but I am afraid that printing will be bad.

Most graphics I bring in are from Photoshop CS5. I make sure they are 300DPI to start and recently learned they should not be in RGB mode but CMYK.

The images I should also mention when placed are very small and I have to scale them to be the correct size. I do not know why they do not place as their original size. So basically it is small size and blurriness.


Any help regarding this matter is appreciative. I am new at Illustrator and want to learn more from it since it seems like a great tool to use for printing.

Thanks,

Victor

I believe the solution to your problem starts in photoshop. Most printers require resolution to be 2X the lpi (lines per inch) and the most common line screen is 150 lpi (133 or 175 are the next most common), so hence 300 dpi (dots per inch) standard resolution requirement. Open your image in photoshop >> Image >> image size >> uncheck resample image >> change your resolution to 300 dpi if it is not and save. I bolded that cause thath setting is very important, and you will need to become intimately familiar with hwo everthing in image size works. This unchecking will not add or remove pixels, but will adjust the size of your image if you change to 300 dpi.

Now when you place the imahe in ilustrator, you will know that your image is exactly 300 dpi. If you scale your image smaller, no problem your effective resolution will be >300dpi adn that never hurts. If you scale your image larger in Illustrator, then you know that your resolution will be less than 300 dpi. You can now better assess the quality of your image reproduction.

Thank you Mike I will do that. Just to follow up can this be done to already existing images?

Also since I changed to CMYK mode I should just leave it there right?

Yes ofcourse, just make sure you uncheck resample image before clicking on OK. You will notice no delay when you hit ok, because this is a very easy task for Photohsop and pixels are not being resampled.

There are times when you will may want to resample(but that is antoher topic), and you will notice some processing time after hitting ok, the higher res image the more processing.
