Device Options for Epson based Driver

NOTE: This information comes directly from the Kothari user manual – make sure you give it a thorough reading to better understand what it is capable of.

a. Printer name

b. Underbase option: This underbase option will allow you to select whether the printing is for white underbase printing or for color data printing. This option is disabled when the printing is on ‘white printing base’ (see ‘c’).

c. Printing background: It allows you to select the color of the printing base. It can be one of the following:

  • White
  • Black
  • Color
  • Dark Color 

d. Resolution: This option will specify the resolution at which the user wants to print with his printer. The resolution is displayed in DPI. Here the string specifies horizontal and vertical resolution. If only one is given then in those cases both horizontal and vertical resolution are same. Higher resolutions produce graphic images that are sharper and show finer detail.

e. Color appearance: Select the output color mode which is by default selected as ‘Colored’.

f. Microweaving: This option allows the printer to generate superior output because graphics data is reordered and is printed in finer increments. It reduces the possibility of banding, the light horizontal lines that can mar an image.

g. Print Direction: This option allows you to set the printing direction. It can be unidirectional or bidirectional or automatic.

h. Dot size: Using this option you can set the size of the dot for printing.

i. Dots used: Specify the combination of dots to be used for generating printing data. Availability of this option depends upon “Dot size” selected.

j. Wet on wet passes: Number of passes to be printed on same position.

k. Weave overlap (in %): Specify in percentage by how much amount you want to overlap two passes. Specifying value greater than zero will reduce the banding between the passes (resulting in improved print quality) but will also increase the print time.

l. Optimize Ripping: Checking this option will increase the ripping speed.

m. Layering: Specifies the layering method. It can be any of the options mentioned below.

  • Multi Pass: Each layer will be printed in a separate pass.
  • Wet On Wet OnePass: All the layers will be printed simultaneously in a single pass, (i.e. the layers will be printed when the other layers are wet and not dried yet).
  • Wet On Dry (Adaptive) OnePass: All the layers will be printed in a single pass, but there would be enough time for the layers to get a bit dried before the other layers are printed on them. This normally gives better results than the ‘Wet On Wet OnePass’ method in which layers are printed even when other layers are wet.

n. Layers count: Enter the no. of layers of white underbase or color data to be printed depending on the option selected currently. This option will only be enabled if you are printing layers in multiple passes.

o. Secondary Resolution: When layers are to be printed simultaneously i.e. using wet on wet or wet on dry One Pass methods, the printing settings of each pass can’t be specified separately. This option enables you to specify the resolution of the secondary passes. The available secondary resolutions are based upon the primary resolution set for the printing of the combined pass.

p. Advanced head control (Nozzle utilization in %): This option is used for masking the nozzles to use for printing. By using this option we can disable starting and trailing nozzles of the print-head from printing. This option is useful in mainly 2 cases. o Some of the starting or trailing nozzles are blocked, and then the user can mask this area and can use rest of the printhead for printing. o In case of printing on Rotary devices only small middle region of print-head is required for printing and in this cased user can mask unwanted top and trailing nozzles.

q. Banding correction: Perform settings for media feed compensation. This corrects the errors in the amount of feed of the grit rollers due to the type of media used. Correcting the amount of feed improves the dot positioning accuracy in the feed direction, which can help in enhancing the image quality.

r. Feed Registration offset (in mm): Registration offset (in mm) specifies the feed direction offset between the white ink layer and the color ink layer.

s. Scan Registration offset (in mm): Registration offset (in mm) specifies the scan direction offset between the white ink layer and the color ink layer.

t. Dry time per scan: Specify the time (in milliseconds) for which the head waits before printing each line.

u. Dry time before reprint: This setting allows the control of the amount of time (in seconds) after which the next layer is to be printed.

v. Restore to factory default: On clicking this option the printer setting in the software will restore to the default settings.

w. Restore to last settings: On clicking this option the last settings that were set by the user as the default will be restored.

x. Set as default: When user clicks this button then the current setting will be set as the last used settings and these settings will be loaded automatically when the user selects this printer next time or clicks the button ‘Restore to last settings’.

Some of the options referred in the device options page (e.g. Banding Correction, Dry Time etc.) may be available / unavailable in your software depending upon the version you use.

Wet On Dry (Adaptive) OnePass method will be available only if it is supported by the selected printer.
