Optimal TIF file resolution for QTR?

2017-02-27 by dtrout@...

I know from experience when using the standard Epson driver on the x900 printers that best results are obtained by NOT allowing the driver to do any resampling to the native printer input resolution when printing files, and instead you should ideally send the driver either a 360ppi file (or 720ppi if you also enable "Finest Detail" in the driver settings). Doing it this way lets you optimize any necessary resampling outside the driver and the driver will not have to do any resampling itself (which is generally not as good).

With QTR, I'd like to understand its resampling behavior. Consider the following cases:

1. Input TIF < 360ppi
2. Input TIF = 360ppi
3. 360ppi < Input TIF < 720ppi
4. Input TIF = 720ppi

I'm going to guess it is "QuadToPrinter" where any resampling would occur. In any case, how exactly does QTR behave in the four cases above on x900 printers?

Thanks, Dave
