Epson Stylus CX4700
Variable-Sized Droplet Technology
The best-sized ink droplet for the best printing results
The Stylus CX4700 features Variable-Sized Dot Technology (VSDT) - another unique Epson development in inkjet printing. By incorporating Ultra microdots and the ability to print with different droplet sizes, VSDT is a major step forward in improving print quality and speed.
Ultramicrodots
With the Stylus CX4700, Ultra microdots are incredibly small ink droplets, between three and six picolitres in size. The dot diameter is up to four times smaller than that of a human hair and is incredibly close to the limit of resolution for the human eye. Achieved by virtue of the absolute control over ink by the Epson MicroPiezo print head, Ultramicrodots deliver prints with much finer detail, less graininess and smoother gradations.
Note: 1 picolitre (pl) = 0.000 000 000 001 litre
Different Size Droplets
To bring about an increase in print speed, Epson developed Variable-Sized Droplet Technology (VSDT) - a major advance that counters the negative impact on speed brought about by an increase in the number of dots per print due to the introduction of Ultramicrodots.
Under the control of the Epson Photo Enhance printer driver, up to six different droplet sizes can be produced on demand - choosing the appropriate size for the area of image being printed. It's like painting a room; you use a large brush for quick coverage of large areas and smaller, finer brushes for areas of detail.
