Light Canvassing Questions 1 1

[RadishRadio]

I was recently returned a SS scored an 8.5. I was certain it was a NM copy. Grader notes were "light spine stress and light canvassing". I elected not to press on submission because to my eye there were no pressable flaws. I did note minor stress to the lower spine and was not expecting 9.8, but 8.5 was a surprise (shock actually). 

Questions are: Does anyone have a good definition of "light canvassing"? Would light canvassing be corrected with a CCS press? Is this something I should have noticed?

I believe this gets a 2+ score bump if the answer is yes to pressing. If no, I will be happy with my 8.5 because it's probably the most beautiful 8.5 copy in the census. /s - Whether I would choose to re-submit after such strict grading on a 50 year old book is another question. Especially with the SS expense that went into the submission to begin with.

Thanks in advance.

Canvassing?  Do you mean creasing?

I think canvassing means multiple dimples on covers that were not pressed out. Not defined in Overstreet so better pony-up to buy the definitions in 'How to Grade like CGC' official book for X-mas?

 hadn't heard this grading term before 

From KaptainMyke

"CANVASING Fine tiny square gridlike patterns across surface of book cover. This is caused by using too much pressure and/or re-using teflon paper sheets."

Canvassing is usually the result of using the wrong materials when pressing a book. I don’t see it as much as I used to, so hopefully people are getting educated on the correct materials to use when pressing a book.

It’s likely from those rubber or foam pads that come with the heat presses.

Sometimes, yes. Other times it’s the materials used. Either way it’s damage to the books.

Thank you for the detailed responses and pictures. I’m not seeing the pattern here, but there is light surface stress to the one corner. I could possibly benefit from a proper press is what I’m taking from this. Assuming CCS would need to perform it as it requires a case crack on a SS book?

Last I heard, yes, CCS is the only ones that can press SS books nowadays.
