Problems Printing on Gloss Media

Post by Lego » Fri Sep 30, 2011 9:56 am

Currently using SGP 220g gloss media. We've been unable to find a profile for the media but were told by our supplier to use GPPG for best results. However it seems to be putting down too much ink, and drying times are way too long.

Just wondered if anyone has experienced this and what to did to solve it

Regards

Hi Lee,

Yould try copying the profile in Media Explorer and then lowering the overall ink limit, the best way is tomprint out the ink limit chart to determine how much ink is acceptable, have you tried any of the other profiles such as GPPM or GPPG?

Hi Lee,

Once you have printed the chart you should see how much ink is overly wet or bleeding into other colours

From this you can then can set in the individual ink limits to match your findings.

Then save the profile and try this with your job.

Hi Lee

Just wondering how you got on adjusting the ink limits in the profiles??

Did it improve the print quality to meet your requirements?

Hi Rod,

I've been playing with ink limits. How do you interpret the "Ink Limit Check Chart" results?

Hi Mal

There are a couple of ways you can look to use the charts (colour adjustment, individual colour limits, combined colour ink limits) but in basic terms, you will look to use the charts to determine the ink limits of the media with given heater temperatures.

You can read the chart and determine where you think the media struggles to accept more ink and as a result the mottling starts to happen. You can then limit the maximum ink limits to try and maintain a good print. It is important to keep in mind that adjusting ink limits will at some point effect colour accuracy so it can be a complicated process.

I hope this helps a little but can I ask what you are looking at ink limits for and can your media supplier help?

Hi Rob,

I've been using a 200gsm gloss paper (from Doro Digital) for quite some time with good results, but thought the paper was a little heavier than I needed. So, I bought some 140gsm satin paper (again from Doro) and things have been good with print qualiy just as expected.

I was printing onto it this afternoon when another forum member raised an issue viewtopic.php?f=21&t=499 with the very paper I was using. To cut a long story short, I have done some print tests and realised that even with the dryer on 50, the ink can remain wet for quite some time after printing. This is particuarly the case when black is applied. I was just wondering how to reduce the amount of black put down inorder to speed up the drying time.

It's not a big issue to me as I am able to leave the printed item flat to dry, but if I was using a take up roller or had to handle it, it would ruin the print.

Hi Mal

It is hard to adjust an indiviual ink limit without effecting other colours that use this ink. With some papers, it is common that there will be a slightly longer drying time than say a vinyl and to be honest there is not a great deal you can do apart from look at other papers...

One tip though - try not to leave your prints laying flat to dry, especially in rooms where there is little circulated air. The reason being that solvent gases are heavier than oxygen so your prints will out-gas and then 're-wet' as the solvent gases fall back on the material. I would instead look to see if you can suspend the prints vertically over a banister or perhaps a washing line if you have the room, as this will allow the gas to roll down and off the media.

Hope all is well.
