ShinHan Touch Markers can be very hard to find information on and where to purchase. They are HUGE in the asian market and are made in Korea. I found them sold at Dick Blick and the price was much less, I got them for $2.09 per marker on clearance (ShinHan is coming out with a new marker style early summer 2011 which will be refillable and replaceable nibs as well as brush styles). I also got a few Dick Blick brand markers to fill in colors I didn't have. Touch are also available online at Pearl Arts, Jerry's Artarama and several people have good results on Ebay. Some stores carry them locally.
So back to the mottled Copics. I posted on Split Coast Stampers (SCS) asking if anyone knew why I was having this problem with Copic? I didn't get very many responses but had some good suggestions that it might be the paper, inadequate saturation or using not using enough ink, ect.
Well, I spent good money on these Copics and I really want them to work and look nice so I had better find out what is going on. I was given some different paper samples by some SCS so I decided to see if it is my paper and what more or less ink would do.
After seeing the Copic results, I decided to see how the Touch markers compare and also did one swatch with a Dick Blick marker.
Very interesting results...and not in Copics favor. But some very useful findings about what papers work better with Copics and which to avoid. Paper definitely has an effect on Copics, as you will see in the following pictures. They also effect Touch and Blick, but not to the degree as Copics.
All papers are layed out the same way - Copics on top, Touch below and the Lilac is Dick Blick. Each color has the same number of strokes, the darker part of the color has 3 strokes, the lighter shade at the bottom is a single stroke. Looking at the back of the papers, they are all saturated at the same level. I have picked out the closest in color and hue of my Touch markers to match my Copics.
To define the problem clearer, I am finding Copic inks "mottle" when they dry. This means that the ink had lighter or white specks throughout, rather than consistent coverage.
PTI 110 - Obvious mottling on G07, YG 23 and YG 45 Copic. Some mottling on Touch 100 and maybe a tad in 102, but at acceptable level. DB (Dick Blick) looks pretty good also.
Copic Blending: This is a smmmoooth paper. The markers move nicely on it. However, I found that all of the pens can leave puddle of wet ink on top. It quickly absorbs in but if someone isn't careful, I think they could smear this puddle before it dries. Mottling on G07, YG23, YG45, E44 Copics. Trace mottling on 47 and 100 Touch and DB. This mottling is a bit different. It almost looks like there are shiny areas embedded in the paper or maybe the slick coating on this paper isn't consistence. When this is looked at in person, it looks like shiny flecks.
Bienfang Smooth Bristol Board. This is one of the better/best paper for Copics. Mild mottling, the most noticeable is G07. Touch and DB look very nice, no mottling.
