 Re: new print head still bad white
If you want to eliminate the printer as the problem - set your white ink resolution as high as possible (maximum white), thoroughly saturate a shirt with pre-treatment and then press until dry. Now try to print, if you are getting good white then the issue is either the way you have ben pre-treating or the resolution at which you have been printing your white layer. If the white is not good, then you have an issue with the printer or the RIP.
Hope this helps! |
