Avoid Printing Large 

White Space Areas

Do not add white space to an image to center it on the media, 

instead use the center media option in the PosterShop Layout 

Preview dialog to center the image. Adding white space to the 

image increases the print time and may dry out the nozzles 

resulting in over-spray and banding.  Turning on the regular 

stripe on the away side of the image, will help prevent the 

nozzles from over-spraying.

Imaging on a new 

media 

When imaging on a new media for the first time (i.e., you do not 

have a media model for the media), we recommend that you 

guess at an appropriate ink restriction level and heater duty 

cycle.  Then print either a test image or the job to be printed prior 

to doing linearization.  Once reasonable ink restriction values 

and heater duty cycles are selected, linearization and ICC 

profiling can be done, if required.

Imaging off the 

media

If anything is printed off the media (e.g., diagnostic stipe or a 

bleed) use a sacrificial scrap piece of media - either the same 

height or up to 1 mm less. Failing to do so causes ink to 

accumulate on the nozzle plate and banding and over-spray.

Additional drying, 

printing uni-

directional vs. home/

away carriage 

delays.

In general, it is better to print uni-directional instead of adding 

home and away carriage delays.  

Reasons: drying uniformity, speed and image quality. 

Drying: unidirectional printing has uniform drying while the ends 

of a bidirectional print always have less drying time than the 

middle of the print in the carriage direction.  

Speed:  the carriage prints at 34”/sec and retracts at 40”/sec 

when printing unidirectional.  This means that for a 40” print a 

home/away delay totaling more than a second would be slower 

than printing unidirectional. Image quality is better with uni-

directional as no bi-directional alignment is required.
