Solving color quality problems

This section helps answer some basic color-related questions and describes how some of the features provided

in the Quality Menu can be used to solve typical color problems.

Note: Read the quick reference page entitled “Print quality and troubleshooting guide” which provides

solutions for common print quality problems, some of which may affect the color quality of the

printed output.

Frequently asked questions (FAQ) about color printing

What is RGB color?

Red, green, and blue light can be added together in various amounts to produce a large range of colors observed

in nature. For example, red and green light can be combined to create yellow light. Televisions and computer

monitors create colors inthis manner. RGB color is a method of describing colors by indicating the amount ofred,

green, and blue light needed to reproduce a particular color.

What is CMYK color?

Cyan, magenta, yellow, and black inks or toners can be printed in various amounts to produce a large range of

colors observed in nature. For example, cyan and yellow can be combined to create green. Printing presses,

inkjet printers, and color laser printers create colors in this manner. CMYK color is a method of describing colors

by indicating the amount of cyan, magenta, yellow, and black needed to reproduce a particular color.

How is color specified in a document to be printed?

Softwareapplicationstypically specifydocument colorusingRGB orCMYKcolorcombinations.Additionally, they

commonly let users modify the color of each object in a document. Since the procedures to modify colors vary

depending on the application, see the software application Help section for instruction.

How does the printer know what color to print?

When a user prints a document, information describing the type and color of each object in the document is sent

to the printer. The color information is passed through color conversion tables that translate the color into

appropriate amounts of cyan, magenta, yellow, and black toner needed to produce the desired color. The object

type information lets different color conversion tables be used for different types of objects. For example, it is

possible to apply one type of color conversion table to text while applying a different color conversion table to

photographic images.

Enhance Fine

Lines A selection to enable a print

mode preferable for certain

files containing fine line

detail, such as architectural

drawings, maps, electronic

circuit diagrams, and flow

charts.

Enhance Fine Lines is not a

menu item. This setting is

Should I use the PostScript or PCL emulation driver for the best color? What driver settings should I use

for the best color?

The PostScript driver is strongly recommended for best color quality. The default settings in the PostScript driver

provide preferred color quality for the majority of printouts.

Why doesn't the printed color match the color I see on the computer screen?

The color conversion tables used in Auto Color Correction mode generally approximate the colors of a

standard computer monitor. However, because of technology differences that exist between printers and

monitors, there are many colors that can be generated on a computer screen that cannot be physically

reproducedon acolorlaserprinter.Colormatchcanalsobeaffectedbymonitorvariationsand lightingconditions.

See the response to the question “How can I match a particular color (such as a color in a corporate logo)?” on

page 6 for recommendations on how the printer Color Samples pages may be useful in solving certain

color-matching problems.

The printed page appears tinted. Can I slightly adjust the color?

Sometimes a user may consider printed pages to appear tinted (for example, everything printed seems to be too

red).Thiscanbecausedbyenvironmentalconditions,paper type,lightingconditions,oruserpreference.Inthese

instances, Color Balance may be used to create more preferable color. Color Balance provides the user with

the ability to make subtle adjustments to the amount of toner being used in each color plane. Selecting positive

(or negative) values for cyan, magenta, yellow, and black under the Color Balance menu will slightly increase (or

decrease) the amountof toner used for the chosen color. For example, if a user believes the overall printed page

to be too red, then decreases to both magenta and yellow could potentially improve color preference.

Is it possible to increase the gloss in the printed output?

Obtain additional gloss by printing using the 1200 dpi Print Resolution Setting.

My color transparencies seem dark when projected. Is there anything I can do to improve the color?

This problem most commonly occurs when projecting transparencies with reflective overhead projectors. To

obtain the highest projected color quality, transmissive overhead projectors are recommended. If a reflective

projector must be used, then adjusting Toner Darkness settings to 1, 2, or 3 will lighten the transparency. Be

sure to print on the recommended type of color transparencies. For more information, see “Understanding paper

and specialty media guidelines” in the User’s Guide on the Software and Documentation CD.

Color Saver must be Off to adjust Toner Darkness.

What is Manual Color Correction?

The color conversion tables applied to each object on the printed page when using the default Auto Color

Correction setting generate preferred color for the majority of documents. Occasionally, a user may want to

apply a different color table mapping. This customization is accomplished using the Manual Color menu and the

Manual Color Correction setting.

Manual Color Correction applies the RGB and CMYK color conversion table mappings as defined in the Manual

Color menu. Users may select any of five different color conversion tables available for RGB objects

(sRGB Display, Display—True Black,sRGB Vivid, Off, and Vivid) and any of four different color conversion tables

available for CMYK objects (US CMYK, Euro CMYK, Vivid CMYK, and Off).

Note: The Manual Color Correction setting is not useful if the software application does not specify colors

with RGB or CMYK combinations, or in certain situations where the software application or the

Color quality guide

Page 6 of 7

computer operating system adjusts the colors specified in the application through color

management.

How can I match a particular color (such as a color in a corporate logo)?

Occasionally, users have a need for the printed color of a particular object to closely match a specific color. A

typical example of this is when a user is trying to match the color of a corporate logo. While instances can occur

in which the printer cannot exactly reproduce the desired color, users should be able to identify adequate color

matches for the majority of cases. The Color Samples menu item can provide useful information in helping to

solve this particular type of color-matching problem.

The nine Color Samples values correspond to color conversion tables in the printer. Selecting any of the Color

Samples values generates a multiple-page printout consisting of hundreds of colored boxes. Either a CMYK or

RGB combination is located on each box, depending on the table selected. The observed color of each box is

obtained by passing the CMYK or RGB combination labeled on the box through the selected color conversion

table.

The user can examine the color samples pages and identify the box whose color is the closest to the desired

color. If the user finds a box whose color is close to the desired color match, but the user would like to scan the

colors in that area in more detail, then the user can access the Detailed Color Samples by using the printer

Embedded Web Server interface, which is only available on network models.

The color combination labeled on the box can then be used for modifying the color of the object in a software

application. The software application Help section provides instructions for modifying the color of an object.

Manual Color Correction may be necessary to utilize the selected color conversion table for the particular

object.

Which Color Samples pages to use for a particular color-matching problem depends on the Color Correction

settingbeing used (Auto, Off, or Manual), the type of object being printed (text, graphics, orimages), and how the

color of the object is specified in the software application (RGB or CMYK combinations). When theprinter Color

Correction setting is set to Off, the color is based on the print job information; no color conversion is

implemented. The following table identifies which Color Samples pages to use.

Note: The Color Samples pages are not useful if the software application does not specify colors with

RGB or CMYK combinations. Additionally, certain situations exist where the software application or

the computer operating system adjusts the RGB or CMYK combinations specified in the application

through color management. The resulting printed color may not be an exact match of the Color

Samples pages.

What are Detailed Color Samples and how do I access them?

This information applies to network models only.

DetailedColor Samplesare pages similar tothe default pages ofcolor samples accessible from the Quality Menu

on the printer operator panel or from the Configuration Menu in the printer Embedded Web Server. The default

color samples accessed by these methods have an increment value of 10 percent for Red (R), Green (G), and

Blue (B) values. Collectively, these values are known as RGB color. If the user finds a value on the pages that is

close, but would like to scan more colors in a nearby area, the user can use the Detailed Color Samples to input

the desired color value and a more specific or lower increment value. This lets the user print multiple pages of

colored boxes that surround a specific color of interest.

ToaccessthepagesofDetailedColorSamples,usetheprinterEmbeddedWebServerinterface.SelecttheColor

Samplesoptionwithinthe ConfigurationMenu.Ninecolorconversion tableoptionsandthree buttonscalledPrint,

Detailed, and Reset are shown on the options screen.

If the user selects a color conversion table and presses the Print button, the printer prints the default color

samples pages. If the user selects a color conversion table and presses the Detailed button, a new interface

becomes available. The interface lets the user enter individual R, G, and B values of the specific color of interest.

The user can also enter an increment value that defines the difference between the RGB value that each color

box differs by. If the user selects Print, a printout generates which consists of the user-specified color and the

colors that exist near this color based on the increment value.

This processcan be duplicated for Cyan (C), Magenta (M), Yellow (Y), and Black (K)color conversion tables, too.

Collectively, these valuesare known as CMYK color. The default incrementis 10 percentfor Black and 20 percent

for Cyan, Magenta, and Yellow. The increment value defined by the user for Detailed Color Samples applies to

Cyan, Magenta, Yellow, and Black.
