This type of manufacturing defect can be fixed by adjusting the settings and is not a vinyl or glue issue.
Essentially ghosting is caused by a change in the surface texture. This is caused by the vinyl becoming over stretched on the edges and the center part of the component which is discolored is a section of the vinyl that was not stretched at the same rate as the other areas.
Typically this issue only happens on membrane presses and not on vacuum presses. The reason is that the membrane is trapping the vinyl down to the door. Raising the membrane for a vac to get the vinyl stretching evenly then lowering the membrane to finish up the detail. Various presses have different functions so this needs to be discussed.
In cases where your membrane press does not have the ability to raise the membrane for a vac stage you can try to move the parts further from each other. This gives more vinyl between each component and can reduce the over stretching.
If both cases above do not work please feel free to contact your laminate sales rep and they will get a tech expert to help fix the issue. It can be solved.

Are you able to post a pic of what ghosting/shadowing looks like? We have a line appearing on the edges we are trying to work out what it is. Thanks, Adrian
I don't currently have an image however if you can imagine the perimenter of a single cabinet door looking lighter than the center but in a non uniform way.... that's ghosting. Please feel to also email me via Mark at Dackor . com (all together no spaces and I can help irregardless of who's material you are using.
We have the same issue recently. The shade is along the stiles and rails on shaker doors, and a halo on slabs. We tried to adjust temperatures, heating time, and also add the vacuum time before the membrane comes down. Sometimes it worked and resulted in a lighter or smaller halo, but it is still there. I am thinking if it is related to the temperature of the vinyl itself as we basically put the vinyl roll in production as soon as it has been received. Vinyl rolls are from northeast of the US. Does it make sense that the cold weather makes the vinyl more brittle? When it is heated up, the stretching marks show up. Many thanks in advance!
Helen, Thank you for your comment / question. As I mentioned in the post most ghosting is caused by the surface being stretched not at the same rate as the center section. On a shaker door that has ghosting it is a bit more of a challenge because the material can also get hung up on the stiles and rails. If you are having over stretching on the stiles and rails you could try to separate your doors a bit more if using pedistals to give more vinyl or you may want to do a longer preheat. A longer preheat could soften a bit more and enable the vinyl to stretch more evenly rather than being forced into compliance with the membrane. You can contact me by email at mark @ dackor.com and I can help you even if its a competitor's vinyl. We will help companies irregardless of the material.
