eco sol ink and outgassing

[burzek]

hey everyone,

still pretty new to the industry and understanding the media/ink/machine.

I have a Roland vs640i eco sol 2 printer.

I have a customer who wants a sign tomorrow.

It doesnt need to be laminated.

It is to be installed on a 900x1200mm aluminium composite panel.

My question is - if I print it this morning, do I still need to wait 24 hours for it to outgas, even if its not getting laminated?
Or can I print, wait a few hours then mount it onto the composite panel?

thanks Pat, they do want the sign to last for a few years and i originally told them i would laminate it but they mucked around with the artwork which was only finalised this morning. I did explain that I need to outgas prints prior to accepting the job last week but they need it tomorrow morning for a Judging Contest so I said I can do it but cant laminate it.

I was thinking giving it to them for their judging contest and getting it back afterwards to laminate it for them.

I wish i bought a latex printer but wasnt aware about the outgassing until after i purchased the Roland. (i should have done more homework!)

Twaddle. Print it, laminate it, and ship it. Outgassing is the sort of myth one uses to scare small children into going to bed. Even if the print emits more gas that the guys around the campfire in Blazing Saddles, which is most certainly does not, the laminate is gas permeable.

Solvents dry via evaporation, the time it takes is a product of the volatility of the solvent. Usually quite quickly. The notion of waiting 24 or some other number of hours has far more to do with letting the media recover it's dimensional stability and its hardness, characteristics which are inarguable affected by solvent printing, not leaking off gasses.

awesome thanks Bob

I generally use the outgassing myth to give myself more time.... I will say that if you have a lot of dark colours then it is wise to allow some time to dry.

This morning I have job that is going to be picked up in 45 minutes... I printed yesterday and laminated this morning, but the cutter sort of screwed up and I just reprinted and have waited 15 minutes...now I will laminate and recut. I am pretty confident after all these years that there will be no issues with this print.

ditto.... outgasing of eco sol inks shares many similarities with the boogey man.

Sorry that I am a little late to get in on this question. But if you print your sign tonight [ Wednesday], you could lay it out on a table overnight to dry. Then in the morning you could laminate it or just install it on the board. Overnight would give your print lots of time to dry.
