PHOTOGRAVURE TECH-SUPPORT & TROUBLESHOOTING REQUEST FORM
Each purchase of Phoenix or Dragon Gravure papers includes one free troubleshooting consult. Further assistance is available by consultation.
Please provide me with all of the following information possible so I can quickly find the source and cause(s) of your problem. This list includes almost every significant variable that can lead to issues in gravure. The cause of a problem can sometimes originate where you least expect it. Without keeping track of all this data it is impossible for me or you to triangulate the source of a problem, especially in a process with so many variables. Successful gravure starts with thorough note taking and learning how to troubleshoot. It is very important that you be accurate with the info you provide. The info and images you send to us will be kept strictly confidential.
Please copy and paste the below text and info into an e-mail.
