Print scale / registration issue

[dinusha]

Hi, I am experiencing a printing scale issue. I printed an artwork 2 weeks ago and I printed the same artwork today. When aligning the crop marks on the 2 prints, they seem to be misaligned or shrinked when looking from one side. I print on film paper for positive output for screen printing. Also

 

 

 

I am printing using sai hp flexi print version 22. I have attached photos. I didn't make any changes on the original pdf file. Any help would be greatly appreciated.

Have you performed both a paper advance calibration and a print head alignment?

hi, thanks for replying. yes, i have run cleaning, alignment and paper advance calibration on the current media, film.

if i explain correctly, maybe the print is sort of gradually shrinked from left to right abt 1-2mm. fyi, when one crop mark is overlapped and aligned, the other crop mark is our of alignment, means shorter in distance.
