*1

Printing industry standard: In the ISO 13655 standard related to color in the printing industry, color evaluation including fluorescence under D50 light source has become a standard.

*2

D50 light source: It is an artificial light source that is close to natural light and used for color measurement.

*3

Fluorescence: It has the property of absorbing ultraviolet light and using this energy to emit light.

*4

Except when installing polarized light filters.

Provide support for color exchange in the global supply chain

main purpose

Main features

density

Equipped with printing quality management functions such as color matching and dot enlargement

As a new industry standard tool that meets the requirements of business printing and packaging printing, it achieves high production efficiency and high quality at low cost.

• CMYK密度
• dot area
• Dot Gain
• color registration
• Simple density difference
• Printing network area ratio
• Printing plate network increases
• Spot color density

Equipped with target matching function * 4 * 5

Display the color difference between the mixed ink and the target color, and adjust the density to make the mixed color closer to the target color. By using the target matching function, ink color adjustment can be made while using a computer or special software.

• Ideal choice for spot colors or printing colors
• Display color difference and density values
• Display the expected density adjustment to make the mixed color closer to the target color and the adjusted expected color difference

Color difference measurement
→ Display the predicted value, and it is expected that the spot color density with a peak at 400nm will be adjusted from 0.86 to 1.16, resulting in a color difference of 0.48

Equipped with functions that comply with various printing standards

Can perform ISO, JapanColor, GRACoL ®、 SWOP ®、 Qualified/unqualified determination of PSO or user-defined targets. FD-7 and FD-5 are ideal choices for on-site printing quality control.

• ISO、JapanColor、GRACoL ®、 SWOP ®、 PSO Color Set Download

• ISO12647 inspection * 4 * 5
  → Can evaluate color difference separately TVI、 Intermediate adjustment extension
• Grey balance
  → According to G7 ® Assessment method for evaluation

*4

The target color (color set) must be set using the accompanying FD data management software FD-S1w.

*5

The support conversion function can convert target values for evaluation when the support conditions of the sample do not match those of the target.

Measuring instruments that comply with ISO 13655 measurement condition M1

• Konica Minolta's proprietary VFS (Virtual Fluorescence Standard) technology enables L * a * b * measurements that comply with ISO 13655 measurement condition M1.
• FD-7 and FD-5 can perform measurements that comply with all four measurement conditions of ISO 13655. Measurements that comply with M1 can be achieved through Konica Minolta's proprietary VFS (Virtual Fluorescence Standard) technology, while measurements that comply with M0 (CIE light source A) and M2 (illumination with UV cut filters) can also be achieved. In addition, testing in compliance with M3 (M2+polarizing filter) can also be conducted by installing the accompanying polarizing filter.

Can perform scanning measurement (FD-7 only)

Spectral data output (FD-7 only)

• After connecting to the computer, spectral data under various light sources (380nm~730nm) can be obtained.
• After connecting to the computer, the spectral radiance data of ambient light (360nm~730nm) can be obtained.
• Suitable for research and development.

Measurable ambient light (FD-7 only)

It can measure the illuminance value * 6 and color temperature of the ambient light for visual evaluation of the light source box or other sources.

The measured ambient light can be registered as a lighting source * 7

When using traditional instruments to measure printing quality on materials containing fluorescent whitening agents, the measurement results often differ significantly from sensory evaluation. This product can calculate the chromaticity value of the tested light source (closer to on-site sensory evaluation), eliminate color differences caused by the influence of fluorescent whitening agents and heterochromatic aberration, ensure that customers obtain ideal colors, and avoid time-consuming and laborious responses to customer complaints.
