    600 DPI Production Printing

    The impact this can have on the industry is to make 400 DPI devices obsolete for many uses.  As architects embed more photographs, and create more detailed drawings the demand for high resolution printing increases.  There is another interesting phenomenon here.  Architects and engineers have been placing low volume 600 DPI devices in their locations and are becoming accustomed to the quality they get from these devices.  It will be hard for them to accept a lower quality print for production distribution.  We have seen this phenomenon in the past with the Oce 9800.

    If you had multiple black and white TV's in your house and you bought one color TV, how long was it before the other black and white TV's were replaced. 

    One reprographer told me I do not want to put a 600 DPI device in my production operation because my customers will like the quality so much I will have to replace all of my equipment with 600 DPI devices.  This will work if (1) your competition does not adopt 600 DPI, and (2) your customers do not have 600 DPI devices in their offices.  I believe both of these are unlikely.  This doesn't necessarily mean you must get rid of your 400 DPI devices.  As we all know, the contractors do not care if it is 600 DPI or 400 DPI, but this would mean you need a workflow to separate contractors work from architects.

    Wow. Just... wow. I cannot, with the naked eye, tell a 300 DPI hairline from a 400 DPI hairline (1 pixel). I can barely see a single 400 dpi pixel.

    Embedded photos? I'm more likely to see embedded JPGs in PDFs looking all jaggy or halftoney (depending on how I convert it to a TIFF). Heck, one contractor uses multiple shades of robin's egg blue, thus requiring us to scan each page twice so the halfsizes don't get too dark to read, but each shade is distinguishable from the other.

    I scanned some old blueprints today... yes, real white-on-blue-prints. I realized there were no nice gradient shades, no halftone dots, nothing but white lines of varying thicknesses. Except for the fragile paper, it was quite a relief.

    I am NOT looking forward to 600 DPI archival scanning. "Whaddya mean it took three CDs? It was just 167 pages!"
