When I place images in Illustrator CS5, I face the following problems.
- I have a AI-CS5.1 file which is 902 KB in size.
- I have a image file in JPG format which is 618 KB in size. The File is 1600 X 1200 and at 180 dpi. Adobe Photoshop "Image Size" shows it at 5.49M "Pixel Dimensions".
- When I place the file in Illustrator and resize to 460 X 330, the size of my AI-CS5.1 file increases to 11,366 KB. I have to do this for many images and many AI files as I place around 5 to 8 images in my AI files. This causes the size of my AI files to increase from 150,000 KB to 250,000 KB. This in return cause my files to take from 1 to 2 minutes to open. Also when the AI files are saved as PDF, the Acrobat files also have huge file sizes from 120,000 KB to 200,000 KB.
- I tried to open the image file in Adobe Photoshop CS5 and resize/resample to my required size of 460 X 330. Than I place the image file (Which now has a size of 193 KB and 460 X 330). However when I do this, the size of the image in ILLustrator turns out to be 184px X 132px.
All my Raster Settings are at 300 as this is for print. I have no idea why my image file when opened in Adobe Photoshop CS5 has different size from where when I import it in Adobe Illustrator CS5.1. I tried to do this for other files as well thinking that some thing must be wrong with the image file. But the problem remains the same with other image files as well.
I am guessing (the best I can do since I am not a designer) that this problem has to do with the resolution. Nor I am a user of Photoshop. I read Image Resolution, Pixel Dimensions and Document Size in Photoshop to better understand the problem. However I fail to understand the reasons for my problem.
Help would as always be appreciated.
