Improved Print and Color Quality in ImageNest Version 3.5
Monday, August 15th, 2011Version 3.5 is a giant leap forward for ImageNest. Both print quality and Color Quality are significantly improved. Our new print system processes all files in 32 bit floating point and automatically re-sizes them to final print resolution. This change is largely transparent and happens automatically but the difference in print quality is striking. How are we doing this? Here is how printing is done from other applications”
Photoshop, ImageNest 3.0, Apple Preview, Lightroom, Etc:
Customer has a 300 PPI image open in their application that they wish to print. They click Print and send the file to the print control panel for their Epson Printer
Printer Driver resizes the 300PPI image to 720PPI using nearest neighbor (low quality) or Bi-Liner (low quality) interpolation. This happens in 100% of all print jobs that are printed from Photoshop, Lightroom, etc. Why? An inkjet printer has a native resolution that all images must be set to in order to print. The same is true for canon and hp printer but their native PPI is 600 PPI.
Print Driver applies a microweave process that converts the PPI (pixels per inch) to DPI (Dots Per Inch with options for 720, 1440, or 2880 DPI on an Epson printer- Canon and HP microweave to different sizes). Printers don’t put pixels on paper, they print dots on paper and microweaving is the process of converting pixels to dots. There is no Image quality lost in this part of the process but a higher level of microweaving generally results in a higher quality print but a slower print time.
New ImageNest 3.5 Print Process:
Customer has a 300 PPI image open in ImageNest that they wish to print. They click Print and ImageNest interpolates the image to 720 PPI using a very high quality Vector Based Interpolation.
Print driver recognizes that the image is at printer resolution and does not perform any interpolation.
Print Driver applies a microweave process that converts the PPI (pixels per inch) to DPI (Dots Per Inch with options for 720, 1440, or 2880 DPI in the case of Epson printer, Canon and HP microweave to different sizes).
