Convert command loss image Quality (AI to PDF convertor)

[manish]

Hi Friends,

While converting AI file to PDF/JPEG, I found that it loses quality of output file. I think I am missing some parameter with 'convert' command.

I am using the below command
convert.exe -density 288 +adjoin D:\Manish\A.ai -density 288 D:\AA.pdf%02d.pdf -flatten D:\AAd.pdf

Please suggest me the parameters and its implementation to improve the image quality.

Thanks

Regards
Manish

AI image file format is essentially postscript. and Both PS and PDF are image vector formats.

ImageMagick is a bitmap image format! It will convert the vector image to a bitmap image before wrapping that into a vector image format. Bitmap images have a specific density which by default is a low 72 dpi. The result is, as you note horrible.
