3.5.5 Color Verify (Only for VJ-1638)
The 'Color Verify' feature can be utilized to aid the printer operator in checking for and isolating
potential color reproduction variations before they become a visual detriment.
In this function, 14 color patches are printed, and the colors are measure by the optional
spectrophotometer (SPECTROVUE VM-10). If the Color Verify was performed before and the
measured value was saved as the baseline, the color difference from the baseline will be printed
as a result.
TIP
TIP
Printer color reproduction can change over time due to various factors, including environmental (shop
temperature and humidity), age and storage conditions of ink and media, possible lot-to-lot manufacturing
variations of ink and media, and aging of the printer itself (due to mechanical wear). Individually, such
factors may have minimal impact on color reproduction, but cumulatively over a span of time these factors
can lead to color variations that become apparent and potentially detrimental to image quality.
NOTE
NOTE
This function is not shown in VJ-1638W.
Follow the 2 steps below to check the color reproducibility using the Color Verify.
1. Save the baseline
Perform the Color Verify under the condition* of comparison criterion, and save the measured
value (only one baseline can be saved).
* e.g.: To use a new media, after an initial ink charge, before starting the continuous print job,
etc.
2. Check the current color reproducibility (Comparison with the baseline)
When a media or ink is replaced, or when the job that has been printed in the past, is printed
again, perform the Color Verify and compare the color with the baseline to check if there is no
significant change in the color reproducibility.
TIP
TIP
When the Color Verify is executed, the color difference (dE) is printed on the top of each color patch. If the
color difference (dE) is quite large, it means that the color reproducibility has varied from when the baseline
was saved. In general, if the dE is more than 3.2, the color difference in the print result will be visible.
In this function, the color difference (dE) is calculated based on CIE 94*.
* CIE94 is proposed by CIE (International Commission of Illumination) in 1994.

NOTE
NOTE
The optional SPECTROVUE VM-10 is required to perform this function.
For more information about the SPECTROVUE VM-10, contact your local MUTOH dealer.
Before performing this function, make sure to print the nozzle check pattern to check if there is no missing
nozzle.
In order to perform the Color Verify correctly, make sure to specify the following settings same as the
setting when the baseline was saved. If these settings are different, the color difference may become
large.
Each Heater Temperature Setting, Effect Setting, CR Print Width Setting, Overwrite Setting
Use this function with the head height adjustment lever is in the “Low” position.
Since the room environment (temperature, humidity) may affect the print color, create the environment in
accordance with the environment condition described in the operating manual “8.1.1 Printer Specification
Environment Condition”. In addition, make sure to place the media and ink in the printing environment for
2 hours before use.
In this function, the baseline cannot be saved for each media. To perform the Color Verify with a different
media, the new baseline should be saved. (If the media is replace to the one previously used, the baseline
should be saved again.)
The 'Color Verify' feature is intended to be utilized as an aid to the printer operator in checking for and
isolating potential color reproduction variations that can arise over time due to various factors common to
all printing environments; it is a tool intended to help facilitate implementation of on-printer process control.
As such, it is not in-and-of-itself a guarantee of color reproducibility or reproduction accuracy, nor does it
negate the need for color workflow best practices.
Follow the procedures below to perform the Color Verify.
3. Turn ON the printer and load the roll media.
