Fedrigoni have just brought out a new and unusual premium grade paper called X-PER, which should be of interest to many print designers.
It's very white and uncoated, but has a special surface treatment so that colour holds out like coated - very bright, quite striking. The texture is also really good - sort of smooth and toothy at the same time.
The only sheets we can think of that have the same kind of characteristics are Heaven 42, Robert Horne's premium extreme white matt, and Brand X, a downshade 100% recycled uncoated from Fenner Paper (it too has a special surface treatment - we printed the RCA Summer Show catalogues on it last year).
X-PER comes in weights from 100gsm to 320gsm, and it's FSC (Forest Stewardship Council) certified. If you'd like samples and printed swatches, get in touch.
