Paper Chase - The Four Baryt - part 2 of 1 2 3 4 5 6 7 8 9

by Mike McNamee Published 01/06/2010

The underlying base medias provide a good variety of tones and properties. The Platinum Gloss WT is a warm-tone, creamy product, the Platinum Gloss is a brightened, cool blue. The Platinum Lustre is slightly warm and the Canson is almost pure neutral (D65/2° measurements). The Platinum Lustre has a very high reflectivity at 99.4%, the Canson is also bright at 98.5%. The spectral traces indicate that Platinum Gloss contains optical brighteners but none of the others does. This was confirmed when we examined the surfaces in the UV booth.

In terms of grain and curl, the Canson and Gloss WT were flat; the Platinum Lustre and Gloss were curled at the short edge, towards the coated side. As with previous tests run on baryta-like surfaces we anticipated having to open the platen gap to avoid problems with head-strikes.

Settings
Having decided to run bespoke profiles for a consistent comparison, we decided upon the following settings:
Test Printer: Epson Stylus Pro 3800 with Photo Black ink
Resolution: 2880dpi
Media Setting: Premium Semi Gloss Photo Paper, PSGPP
High Speed: OFF


In accordance with best practice (as advised by Epson) we set the media source to Rear Manual. Because the papers were thicker than the default for PSGPP we set the paper thickness manually to 5 units. In accordance with advice (from Hahnemuhle) we set the Platen Gap to 'wide' and increased the Dwell time to 20 units to allow more drying time (in the Paper Config of the driver).
