Can you explain how this is true from a chemistry perspective? If I recall my physical chemistry (and it's been a lot of years since I finished both my undergrad and grad degrees in chemistry) it's the aromatic double bonds in the dye molecules are damaged and it doesn't particularly matter what causes the damage.
It's shipping now with TNT
The samples are as follows:
Glossy: A4X25sheets
Satin: A4X25sheets
Pearl: A4X15sheets.
Satin is luster.Pearl is another type of luster.We are selling more satin paper.Please check.
Who wouldn’t... It was hilarious, and Percy nearly got the winner...The Hat needs to get himself to confessional after Liking that video.
Color is due to conjugated double bonds in a dye molecule. When the bonds are broken, color is reduced.
Ozone breaks a bond due to oxidation. The electrons in the metal atom in a lightfast dye actually help promote the oxidation and destruction of the double bond.
A bit more information has just been provided by Mr Wei Yu of Giant Image about the swellable papers. Apparently last month they determined that the gsm is 220 not 230 as on the website and they have not yet corrected the website. I'm happy with paper 260gsm -300gsm but have reservations about a 220gsm paper as I've found it is easy to put permanent dents in the lighter papers (even 260gsm) unless it is handled very carefully. The HP Premium Plus is 280gsm and my Ilford cheaper inkjet photo papers are 250gsm.the shipment to me is underway, so let's see and wait until it arrives. All my communication with bdgiantimage was about swellable papers.
