用免费RIP软件GutenPrint来驱动打印机（高手来讨论）

报喜鸟

dither Algorithm 中文翻译就是抖动插值算法。是个很高级的色彩像素补偿算法，我认为最好的配置是 adaptive hybrid----可适应的色彩合成抖动算法，而不是默认的default 。供参考

高手，越辩越明

我打照片用adaptive hybrid感觉色偏和过度还不理想，不知道报喜鸟 你的纸张和墨水配置是怎么样设置的？
我的设置是这样：

Hi, Dear 报喜鸟,

In  "Gutenprint driver version 4.2", You are almost right.
But "dither Algorithm --- EvenTone" is now better than Adaptive Hybrid
in version 5.2 for print out photographs (high quality photos) .

EvenTone, This relatively new algorithm yields excellent smoothness in all tones (light,
midtone, and shadow), the shortcoming is slower than most of the other algorithms.
It is somewhat prone to artifacts, including “tearing”, at sharp boundaries. This algorithm
is well-suited for printing photographs, but is not as suitable for printing solid-tone
graphics.

How about Adaptive Hybrid,  This algorithm produces slightly smoother output than
Ordered dithering, at some cost in performance. It uses a fixed pattern in highlights to
avoid artifacts, and error diffusion at higher densities to reduce noise. It is an excellent
choice for printing business graphics due to its lack of artifacts and smooth texture in
darker tones.

By the way, In my initial experience, print out photos on Gutenprint driver, I got
satisfied results in both color tuning  by gutenprint or color management by ICC
profile in Photoshop-gutenprint driver system.

Here is for reference only, due to my poor knowledge about basis of GutenPrint driver.

Any advice or comments are welcome.

大家好...我试过在GIMP里和Photoshop都OK....就是不知如何设定连续打印 （无限长度）,
不知谁能帮帮忙.....

我用的是Windows7, 普通打印全没问题..只是设置不到一张照片要如何连续打印,,.. 在Photoshop也好GIMP也好,,,....只要能设置到无限长度打印...那就无限感激

Info:

Epson Stylus Pro printers (x600, x800, and x880 series) can be supported
to position images correctly on the page and to correctly cut the print
in roll feed mode by GutenPrint latest version 5.2.6

        NOTE: The support for the Epson Stylus Pro 3800 and 3880 are
        experimental and WILL CHANGE SUBSTANTIALLY in future releases.
        It should not be considered suitable for production use at this time.

已几天不见大家回复了，不知道进行得咋样？

回楼上。我也有个问题，就是直接在position里改数值没用，你切换一下窗口，数值就又变回去了。非得用鼠标在左边预览里面拖动图片，才会生效。
除了这个之外，还有上面那个定义纸张的区域，如果是Custom，你的数值怎么改都无效，都会变成原来的数值。
