To: Renderprint users Can a Renderprint output an image from 3DS as a scaled up size but not pixelated? In other words, say I render at 1024×768 in true color with antialiasing, can I print a nice scaled up image on a printer at page size?

Albert, <<1024×768>> Is pretty low res for full page rendering. Most of the images we print at tradeshows and for samples around here start life as at least 2000 x 2000 TGA files. That's the bad news, the good news is you don't have ta' add any extra memory to your plotter to print these beasts at full page size! …(g)… Russ Insight Development go 49'ers

Ok, I can probably render larger than the 1024×768 that I mentioned but my current computer is limited to 16MB (due to crass monitary considerations <g>). Also, the images I want to print will not have very finely detailed images, at least until I can get a better, faster computer with more memory <g>. I can live with an image that looks a bit washed out or fuzzy, but I don't want something that looks like it is made with large pixelated blocks. I spoke to your voice line and am getting some literature. I understand you will support the Epson Stylus Color in the fairly near future, I hope. The Epson would be for test, final print would be at a service bureau.

Albert, <<made with large pixelated blocks>> The current version does an OK job, but we are workin' on it! …(g)… We have many dither patterns and depending on the image some of these do a real nice job of allowing images to be blown up reasonably well. I know what you mean about the memory issue for rendering, I've just reset my Windows memory space to 64megs for R13! …(g)… <<Epson Stylus Color>> We have a test driver but it's to slow for prime time so we are working on it this week soooooooo, maybe soooooooon! …(g)…. In any event if you buy RenderPrint now, make sure you write on the Reg card Epson Stylus so we can send ya' a free driver when it's done! For the time being you use the LQ2550 360 dpi driver.

If you have seen the Epson Stylus printing graphics in hi-res mode, it is VERY slow. So my question is: How can you tell that your driver is slow ? <g> Well never mind, I look forward to news of developments.

Albert, <<your driver is slow>> A fair question. The Epson comes with a Windows driver that is a nice driver. We all know about Windows printing so our target for you as a customer should be to print AT LEAST as fast as a Windows driver. Well, we don't yet! …(g)… Our driver is a partial answer to the problem. We currently support the Epson ESC/P2 coding conventions but have not yet mastered the Microweave coding yet. We are making multiple passes of the print head when we shouldn't be. Our print out looks awesome, it just takes twaice as long as it should, and twice as long ain't no good! …(g)… Russ Insight Development

When you go to print you are always "pixelating" – it just depends on how large the resulting rasters are printed. The point at which the size of a raster signals "aliasing" or "pixelation" is subjective and will vary according to the type of output device: be it continuos tone or screened. If it's screened, then there are several other factors (such as screen size) that influence your image's quality. But sorry to belabor a point – yes Renderprint can output a 1K image to, say, a HP650C and plot a convincing image at 24"x30". Of course it could print a 3kx4k image at that size as well and be near poster-like. – Phil
