Latex 365 Tiling issues

HP Latex 300 Series

#1 darkknight776344 5 years ago

Hi all! A few occasions now whist printing some large tiled jobs the fitters have reported issues with alignment/fit. Double checking back over job history, panels are printed one after the other ( back to back) same settings/file have been used in Caldera. All RIP settings appear to be correct - Scaling at 100% At a bit of a loss now. have any of you experienced similar? Cheers in advance Jay

#1 Hi Jay - take a look at similar posts in this link (likeLatex 360 question or just latex 360...):

Basically it's the temperature, the material and the take-up reel. Take-up reel is pulling too strong the substrate, the substrate is deforming from the middle to the side and if substrate is deforming too much in high temp - you've got the result. And again no matter what "Skew acceptance" you've set when loading, after a long printing the material is skewing... Cheers

Thank you squire! That had been by deductions also. Sadly my MD would not accept this as a reason for the errors.

Gather round latex warriors The most obvious is most rejectable However a few remedies (not always working when many variables are mixing - humidity, substrate condition and so on):

  • make more overlapping (half inch ) we are using sometimes inch to overlap images;
  • lower the temperature if possible;
  • try to set skew as minimal as possible and don't use take-up reel for these prints (also if possible), otherwise you have to load media with take-up reel from the beginning and throw a lot of substrate...
  • check dimensions in files because caldera sometimes i rounding numbers - like you are setting 9.0 and its doing - 8.99
  • and throw some beans and hope Last is mantra of mine for wallpapers Cheers again and best of luck

I suggest to check on the following points:

  • Ensure loading with minimal skew
  • Ensure printer and rollers are clean
  • When loading the TUR cut the edge in the shape of a V and tape only the center
  • Ensure the temperature is as low as possible for the media (you can find profiles for certified media in the HP media solution locator)
  • Adjust the tension of the TUR with the counterweights (contact reseller for information on this part)
  • Print every other tile rotated 180º
  • Ensure that the media advance calibration is done for the media being used.
  • Lower the vacuum
  • Lower the ink density, increase the number of passes, lower temperature, add interswath delay.

Please let us know if you have solved the issue with these recommendations.
