We have it and we say, the paper is supplied from Germany, as well as many other paper/ink products, etc. Now, this particular paper will play a little with the dice, what do we mean?
Problem with marks, they do not have consistent quality. Firstly, depending on which store you order from, the paper will be different. I bought 3-4 of the same with the same specifications and packaging, and in the first one, I had marks on almost half of the papers, which should have lowered the price by half. Then I bought Matte paper from MediaRange from another store and again, regardless of being Matte, it had marks, specifically marks that resemble the back of the packaging. This shows us obvious poor management in orders when they are supplied, if it has the same problem in 2 stores, obviously the supplier or the immediately preceding one is responsible. So if you are a store, please return them and hold the supplier accountable.
Next, the print quality. I purchased 2 papers, I have a professional photo printer with high-quality inks, enough pigment to adhere even to plain paper but diluted enough to be absorbed properly by the paper. So, this particular paper came out more gray like paper, to me and my colleague who checked it, and the prints were always blurry as a result. Secondly, the paper we got from another store was normal as it should be for the prints, considering that the inks were exactly the same from the company. Specifically, for the latest generation Canon Pixma.
So when you buy and see that the paper does not print properly after some adjustments, please ask the store to replace it (do a Photoshop and place the same image a little further each time on the paper and change the prints to see the difference). Generally, I will describe it exactly as my colleague from abroad told me, in Europe and especially in Greece, we have unacceptable paper quality with variations in quality even if we buy from the same factory, so be careful and be more demanding with the paper! The resources of the papers in Europe cannot meet the needs of even basic quality photo printing, and obviously we are not obliged to buy from specific companies.
In summary, the paper may turn out good for you or not, it may come with marks or not, if yes, then immediate replacement! (Because it is paper, simply ask them to send you a new one and the store to tell the factory to perform better quality control!)
