Print tab
The Print tab displays basic processing settings and allows you to access your printer’s Driver Options.
Resolution-
You may set the output resolution here. A higher resolution will generally result in better results but slower output.
The resolution set here is separate from the resolution used by your application.
Setting a resolution in this driver that is higher than the resolution in the application will not necessarily improve the
output.
Density Adjustment-
Select a default density file to apply to all jobs. Select None if you don’t want a density file applied.
Dither Type-
This is the pattern in which the individual dots that make an image are applied to the media. Dots of ink are arranged
to fool your eye into seeing different shades.
Perform Color Correction
- Checking this setting makes incoming jobs use the color correction settings- ICC input and output
profiles that are explained below- of Roland COLORCHOICE RIP Software. If this setting is not checked, incoming jobs are
assumed to already have color correction.
ICC input profile
- This area is only accessible if Perform Color Correction is checked. Three types of ICC input profiles can be
specified:
•
CMYK
has a default setting of High end Swop. You also can specify a different CMYK profile using the Add button.
•
RGB
corresponds to monitor profiles. In addition to the Generic setting, which will provide good results, you can select
other popular monitor ICC profiles.
•
Gray
is the gray component ICC profile. Accept the default setting or use the Add button to locate another.
With input profiles, you can accept the default setting for all three profiles and expect excellent results. The ability to specify new
profiles is an advanced feature, and you should use it only if you have a thorough understanding of ICC profiles and how to apply
them.
ICC output profile
•
Profile
: Output profiles define the characteristics of your printer. An ICC profile is made for each ink/media combination
that is available for a device. From the pulldown list you can choose the profile that is appropriate for your job.
• Image and Vector Rendering Intents
: Before a file can be RIPed, its ICC profile must be translated into CRD (Color
Rendering Dictionary) values. This is essentially the process of truncating RGB color space to CMYK color space. How
to truncate this space is determined by the color rendering intent that you select. Select a rendering intent from the list of
standard PostScript types. With COLORCHOICE you can specify separate rendering intents for vector images and
bitmapped images. Vector images include lines, circles, text, and other non-bitmapped images. Bitmapped images are any
non-vector elements such as photos, or other elements that consist of a pattern of individual dots, and not lines or
