[labnetwork] Transparency masks

[Geil, Bob]

Hi Demis,
  It depends on the printer type. Laser Jet ink seems to work well on typical transparencies<https://www.amazon.com/dp/B085BFLX5V/ref=sspa_dk_detail_0?psc=1&pd_rd_i=B085BFLX5V&pd_rd_w=hldPK&content-id=amzn1.sym.386c274b-4bfe-4421-9052-a1a56db557ab&pf_rd_p=386c274b-4bfe-4421-9052-a1a56db557ab&pf_rd_r=EYSWHGJBCQW57MSB4ZC3&pd_rd_wg=o2gUX&pd_rd_r=f1bfadf1-65c1-493f-9168-c6a3ebaeca82&s=office-products&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWxfdGhlbWF0aWM>. For inkjet printers, you need a film that can absorb the ink:

Best,

You don't often get email from demis at ucsb.edu. Learn why this is important<https://aka.ms/LearnAboutSenderIdentification>
For one of our outreach events we print user’s images onto transparencies, for litho on an MA6.

However we often run into the problem that for some combination of transparencies and printer ink, the ink just rubs right off the plastic transparency, even if left to dry for hours!

We believe that the same transparencies that worked last year, this year had the ink rub off. Do we need to vac seal the transparencies when unused?

If anybody knows what the combo is that works/fails, your advice would be greatly appreciated.
