Hi guys
I am having a spot of bother with subing a glass cutting board and at £6 ago I cant keep going wrong. I have pressed two now. One with the image on top and one underneath. Both have the same issue which is the dark areas are all faded and look mouldy. Both in exactly the same area. I pressed the first at 200 for 300 sec as per listawood instructions the 2nd at 200 for 360 sec thinking that the dark area need some more time. The original image is not the greatest as it has been sent from an iPhone, neither are my photos to good but I hope they show the issue.[ATTACH=CONFIG]2398[/ATTACH][ATTACH=CONFIG]2399[/ATTACH][ATTACH=CONFIG]2400[/ATTACH]
I am using Ricoh, sawgrass power drive and trupix paper. The heat press has no name but does not have any cold spots correct heat all over

Did you position the glass so that corner was in the same place on the press? It's not only the heat plate that can be at fault but also the mat. The larger the item being printed then the more you notice discrepancies. 200c for ricoh should certainly mean it is not heat. Getting even heat can be down to pressure plus the above mentioned. How well did the image print onto the paper?

The image was fine on the paper, I have pressed other large items including slates and have not had any issues with uneven pressure I also have pressed 4 unisub coasters at once with no issues. I am not sure if the board was in exactly the same place each time or if the picture was orientated the same way. I have noticed that there seems to be a great variation in times from different suppliers.

I will add though that inks from ricohs need less time i also print with the glass on top

I was worried about the pressure but it was very firm, in fact I thought I might break the board.

It looks to me that the dark colours did not sublimate properly or is it because it cooked it for to long?

Shouldnt need very firm , what press you got

Good question, I do not know. I bought it on ebay but I know it is not a cheap Chinese one. I have checked the heat plate with a IR thermometer and it is even. I have printed many different items since starting this venture and have followed the cooking instructions found on several sites and have never had a problem. This is my first real issue with a product and it would be one of the most expensive ones. I have been able to press slates ( first time no issues) and flip flops in the press so I know it is even pressure. It is more annoying as I have been asked specifically to provide someone with this item and I have ruined 2 already and now am going to be making a loss on the sale:mad:!!!
I guess I must have just been lucky with all the other items I have produced.

Can you post a photo of your press
