Required illumination for print assessment

1

Can anyone come up with figures for the required illumination needed for print assessment on a wall or a table (in lux or in EV (100ASA)) in a D50/D60 environnement (which is what is required for ideal Piezography conditions, right?) ? Does 2000 Lux (10EV) sound about right?

I suggest slightly cooler than a gallery wall and slightly brighter than a gallery wall. This is a fine-art monochrome process, not commercial pre-press.

The monitor itself should be at 6000k about. Keep a decent amount of light behind the monitor in order to make sure your eyes are not too dilated.

Thank you for that!

I shall make sure to calibrate my screen to 6000k and to keep decent lighting behind it to avoid pupil dilatation.

As for the print assessment wall, I am not sure of the level of illumination required for a “gallery wall”. Can you come up with a figure as an rough guide? 2000lux (10EV) which is the figure I came across, might apply to commercial pre-press… It might therefore be too much for fine-art. An indicative figure would be helpful.

Hi Walker, is your 6000K recommendation a change from what is published in the Piezography manual (5000K)?

thanks.

Yes. It’s my change. The manual was based around CRTs. LEDs really need to be at 6000k

What is the optimum light in Kelvin to exhibit a piezo pro print?

between 2400 - 4700 in my opinion.

Thanks Walker, have made a note of that.
