Head-to-Head Test Specs

by Adam C. Engst

So, now the question comes down to who does a better job of font conversion. We ran two tests, a Type 1 to TrueType conversion and a Type 3 to Type 1 conversion. In both tests, Adobe's New Century Schoolbook Roman was used as a test font. Dave printed his results on an HP DeskJet and an Apple LaserWriter IINT. I printed my results on a GCC PLP II and a GCC BLP IIS. In each case, one aspect of each of the printers was inherently different from the others. The DeskJet is a 300 dpi inkjet printer. Inkjet-based printers usually have a slightly larger dot-spread (dot-size) than a laser printer of equivalent resolution. The LaserWriter IINT is an Adobe Postscript printer based on the Canon laser engine. The GCC PLP II is a QuickDraw printer, so it either depends on ATM or TrueType to do its font rasterizing in these tests. The GCC BLP IIS is an Adobe Postscript printer with the ATM font rasterizer in ROM. Both the GCC PLP II and BLP IIS are based on Oki's LED-based engines, guaranteeing that the dot-size is equal to the resolution at 300 dpi.
