The trick is to create logofuli.png at whatever size you need for the output, containing whatever image you need repeating.

thanks for your reply

I mean the logofuli.png is a fixed png file, how to add some parameter into this command
composite -tile -gravity center logofuli.png myg182_01.jpg ...

I haven't seen color profiles that will convert to CMYK grayscale. I have seen profiles that will convert to sRGB grayscale, so you could convert via one of these and then to CMYK.

Or you could use one of the many other methods to convert to sRGB grayscale, then convert the profile to CMYK.

Let ...

Any color profile can be used with grayscale images. Does that answer the question?

Let me rephrase my question

convert -alpha off -units pixelsperinch 300 Test_RGB_2901_1.jpg[0] -profile "sRGB Color Space Profile" -profile <GrayProfile??> Test_Gray_2901_1.jpg

So which color profile I can use ...

Currently in my conversion I am using the below profile based on color mode

RGB to CMYK (when the input image also doesnt have any color profile)
convert -alpha off -units pixelsperinch 300 Test_RGB_2901_1.jpg[0] -profile "sRGB Color Space Profile" -profile USWebCoatedSWOP.icc Test_CMYK_2901_1.jpg ...

This seems to work by using the clip-path in the image.

convert -quiet Harold_1.tif[0] \
-profile /Users/fred/images/profiles/USWebCoatedSWOP.icc \
-profile /Users/fred/images/profiles/sRGB.icc \
-alpha transparent -clip -alpha opaque -strip Harold_1.eps

This is chopping off the complete shadow ...

When converting the TIFF-CMYK file to EPS-RGB all the flats (knocked out images with a shadow on a transparent layer, saved as a transparent tiff) are showing up with very dark shadow in the output EPS

Sorry for the delayed response guys

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

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.
