Tiff to Eps conversion, output file size is big compared to the file size from Photoshop generated eps file

[HaroldWindt]

Conversion from TIFF-CMYK -> EPS-RGB
Resolution change from 300 -> 120

We had a tiff file and we converted it to EPS using Imagemagick and Photoshop, the resultant output file has a huge variation of size difference on the file system.

Photoshop EPS file - 523992 bytes
ImageMagick EPS file - 15250211 bytes
Can any one explain why ImageMagick is generating a bigger size eps file when compared to Photoshop

Please find the below files

Is one 120 pixels per Inch and the other 120 pixels per Centimeter?

[magick]

Save as EPS2 (or 3) rather than EPS (e.g. convert myimage.tiff eps2:myimage.eps).

Sorry for the delayed response guys

Both are PixelPerInch

Save as EPS2 (or 3) rather than EPS (e.g. convert myimage.tiff eps2:myimage.eps).

I had saved the image as eps2 and eps3, the size has drastically reduced.
Still its no where near to the EPS file generated by Photoshop

Photoshop EPS file ~ 500KB (the file can be found in the main post of this topic)
ImageMagick EPS2 file ~3.5MB https://www.dropbox.com/s/j6wrs1aqukfe8 ... 2.eps?dl=0
ImageMagick EPS3 file ~3.5MB https://www.dropbox.com/s/6q13r6twhswly ... 2.eps?dl=0

I tried doing an identify -verbose on the EPS file from photoshop and the eps2&eps3 file but couldn't find any significant differences to identify what's causing the files generated by ImageMagick to be much bigger.
Any idea what's causing this ?

The Photoshop version is compressed as JPEG. You can also do this in IM:

Code: Select all

convert EB_Photoshop_999G2.eps -compress jpeg -quality 10 eps2:a.eps

The filesize is 64,084 bytes, about 12% of the PS size (but horrible quality).

Converting images to and from JPG is not recommended, as pixels change with every save.
