Transition Saphira UV02 to UV05

Yes and no. The impact depends on whether the spot colors used previously in the existing jobs were close to, or outside of the achievable color gamut of Saphira UV02/UV04.

Spot colors that were already well within the available color gamut are unlikely to show any significant changes. However, spot colors that were at the edge of or outside the previous color gamut may appear different after the upgrade.

With Saphira UV02/UV04, colors that could not be reproduced within the available gamut were effectively clipped to the nearest achievable color. As a result, the printed color could differ from the intended LAB values defined in the color table.

Thanks to the expanded color gamut of Saphira UV05, many of these previously unachievable colors can now be reproduced more accurately. Colors that were formerly clipped are now more likely to fall within the printable gamut and can therefore be printed much closer to their intended LAB values.

In practical terms, this means that color reproduction will generally improve and better match the target spot color definition. However, the printed result may not be identical to what was produced previously, as the system is now capable of reproducing the color more accurately than before.

Yes, some changes may be visible. The improved color gamut of the Saphira UV05 enables a more accurate reproduction of the target colors defined by the simulation standard. Since Saphira UV05 offers a wider color gamut and enhanced color capabilities, it can reproduce common process standards more precisely than Saphira UV02/UV04.

As a result, certain images or objects may show slight visual differences. However, this should be considered a positive effect, as Saphira UV05 achieves a closer match to the intended process standard and therefore delivers more accurate color reproduction.

The following comparison illustrates how accurately the pure process colors defined by the standard can be reproduced.

No. Existing materials and web width settings can be reused and do not need to be recreated.

Yes. Existing output conditions in Color Center cannot be used with Saphira UV05 and must be replaced with newly created output conditions.

As part of the upgrade process, Color Center automatically detects the use of Saphira UV05 inks and disables the existing output conditions. However, these output conditions are not deleted. This allows you to retain and reuse the existing material definitions when creating the new output conditions, eliminating the need to enter the material data again.

In summary, while new output conditions must be created, the associated materials can be reused, making the setup process significantly more efficient.

Yes, existing jobs will be affected. The first time an existing job is opened in Prinect Cockpit after the upgrade to Saphira UV05, a warning dialog will appear prompting you to select the new output condition.

If you have reused the same material names when creating the new Saphira UV05 output conditions, the process is straightforward. In most cases, you will only need to select the corresponding new output condition, after which the job can continue to be processed as usual.

This ensures that existing jobs can be used with the updated Saphira UV05 configuration while maintaining consistency with the newly created output conditions.

Yes, to support the use of Saphira UV05, the Prinect software must be updated to the current supported version available at the time of the ink upgrade.

A good way to prepare for the Saphira UV05 upgrade is to create a test job that includes important customer spot colors, as well as colors that have been challenging to reproduce accurately in the past.

Print this job before the upgrade and keep the samples for comparison. The test job should ideally contain both measurable control patches and visual elements, allowing for an objective evaluation as well as a visual assessment of the results.

After upgrading to UV05, print the same job again and compare the results. This will make it easy to identify the benefits of the expanded color gamut.

First, the Prinect software must be updated to the latest supported version available at the time of the Saphira UV05 upgrade to ensure full compatibility with the new ink set and workflows.

Before the conversion, a machine status printout should be taken while the press is still operating with Saphira UV02 inks. The system is then flushed and converted to Saphira UV05. Once the conversion has been completed, a second machine status printout should be generated with Spahira UV05 to document and verify the new operating condition.

No hardware modifications are required for the upgrade. The existing UV E2C dryer can continue to be used, and there is no change to the maximum printing speed, which remains at 70 m/min.

Converting a Gallus One into a Gallus Five requires both software and hardware upgrades, as well as the transition from Saphira UV02 to Saphira UV05 inks.

First, the Prinect software must be updated to the latest supported version available at the time of the upgrade to ensure compatibility with the new system configuration and Saphira UV05 workflows.

In addition, the dryers in the digital printing unit must be upgraded to Leo LED2 dryers with water cooling. This hardware modification is a key requirement of the Gallus Five configuration.

Before the conversion, a machine status printout should be taken while the press is still running with Saphira UV02 inks. The system is then flushed and converted to Saphira UV05. Once the conversion is complete, a second machine status printout should be generated while running Saphira UV05 to verify and document the new machine setup.

Following the upgrade, the maximum printing speed increases to 100 m/min, providing higher productivity compared to the standard Gallus One configuration.
