Test printouts

Before operation of changing the way of supplying the printer with ink different then original, there is better to make printouts permissive on later comparison of colouristic. It is recommended to print well-colouristic pictures and the best calibration sheet in colour version and also grey, but printed with colour inks. The print of grey picture using colour inks allows to estimate the rate of colouring the greyness, it means balance of colours in different intensity. Original Epson inks in default settings seldom give real greyness.
