Spanish term

valor de negro

Spanish to English Other Printing & Publishing
Hello. This is from a brand identity manual, describing the permitted colour and formatting alternatives for the brand's logo:


"- Fondo con una saturación superior al 50% de valor de negro: se debe reproducir la marca en negativo."


Going into UK English.

Thanks for your help :)

Votes to reclassify question as PRO/non-PRO:

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.

How to tell the difference between "easy" and "pro" questions:

An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)

A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).

Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.

When deciding between easy and pro, err on the side of pro. Most questions will be pro.

* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

Discussion

mediamatrix (X) Jan 25, 2011:
The colorimetry of print and electronic media is very different, and it is helpful to be wary of using media-specific terms in the wrong context. However, in this particular case there is no problem in using a term having its roots in the 'dark ages' of black 'n' white TV, since the meaning is the same in both.
Simon Bruni (asker) Jan 25, 2011:
Thanks for your help Mediamatrix Yes, you're right. The guidelines are explicitly for both paper and digital media. I think both count as 'publishing' to be honest.
mediamatrix (X) Jan 25, 2011:
@Simon You have headed this question as 'Printing & Publishing', but the same rule about displaying the logo as a negative if the background is dark (as implied by the 50% limit) would probably apply also in electronic media: TV, Internet, cinema, etc. But the 50% value might, in such cases, be different. Can you confirm that this particular line from the source text does actually refer to print (i.e. paper), and not to other supports?

black value

I'm pretty sure this is referring to the CMYK (Cyan-Magenta-Yellow-blacK) colour code.

I pasted the wrong one in, which doesn't even work. Hopefully this one will.

Thanks Phoebe.
neutral Jennifer Levey : The fact that it was only 'moderately' clear that the text refers to (...) has been proven by the additional context referring to both print and digital media. It is now 'very' clear that CMYK is irrelevant here, since CMYK is print-specific.

I don't really see how it is (moderately) clear from the context given that it refers to the black level established before CMYK separation.

Peer comment(s):

disagree Jennifer Levey : RGB refers to a number (or a set of 3 numbers) representing the relative mix of red, green and blue in a colour, and it independent of the 'valor de negro' in Asker's context.

Thanks for your comment Robin, sounds like you've got your own term: Saludos, eski
disagree Martin Cassell : black value/valor de negro has a clear, specific meaning: the darkest value reproducible. this should not be confused with "RGB value"

black level

Although more commonly used in the context of TV, 'black level' is also uzsed in the print trade to refer to the reference opacity corresponding to 100% saturated black ink on the support.

neutral James A. Walsh : If it's 'level', surely 'nivel' would be used in the source text?

I'm sure we should be helping Simon to deliver a correct text in English, not proof-reading the author's text.
