Try putting them in a drawer for a few days and see if they still change.
There is also a metallic paper from another company in Texas called Breathing Color. They had sample pack with about 16 different papers, 2 sheets each which included a metallic paper.
They will send you a code, and it is only $8.64 for shipping. I am waiting to try it on my Pro-100.

I found the same one on ebay for $3.00. It works well.
The OP is looking for a Pro grade printer. He will be printing large quantities, so that the smaller ink carts of the Pro 100 would have to be frequently changed. Since these prints are being sold, only OEM inks should be used. LD dye inks would
not give the longevity needed.
You must be hard on the tires. My 2014 A4 has 42,000 miles on the original set.
I have mine since 1962. I picked it up from their factory which was a 4 car garage for$35. Great piece of machinery.
Some of the lower priced homes are never ready for photos. I spend an extra hour waiting as the owner moved things around. Also most of the MLS boards restrict you to the size of your pix. We can shoot up to 12 MP. It used to be 6. We were also limited to 12 pix. Now we up to 50.I felt like it was going duck hunting with a bazooka. I do use a wide angle, but try not to distort.
I just read on the BGR website that a new update for Windows 10 is being released. It is supposed to address the font size problem. It has to be manually downloaded.
Hope this helps.
If you bought it from someone like Best Buy, they can issue you a duplicate receipt. SanDisk will ask you to take pix of the front and back of the card before they issue a RA. Good luck from Henrico VA.
I use this lens on a Sony a77. I am careful to protect the front element. There is a fairly expensive filter adapter that can be fitted to it. Never found a reason to buy one since I use it 90% of the time for real estate interiors.
If I need a filter, I have the Sony 11-18mm lens that uses 77mm filters for exteriors if needed. The Sigma has some distortion at 8mm. Just have to change the composition slightly.
I love it. Enjoy the new ride.
