Thanks for your kind words Gino, appreciated. I so enjoy being barked at like a junk-yard dog.
With this customer-provided file, how was I to know that that particular part of the complex image wasn't correct? It could very well have been designed like that. It wasn't until I imported the file into Illy that I saw it imported differently than it did into CorelDraw. I'm not trying to get away with anything; I fully intend to explain exactly what happened with the customer, I just don't feel that throwing a 4' x 12' banner in the garbage over this is reasonable. If the customer doesn't find it acceptable - with a discount (as I think any reasonable person would), then I will re-do it. It's a banner, not a pair of shoes or tires.
I'm so grateful, you didn't take things the wrong way. You're so considerate like that.
It seems now you changed your direction a tad. You first seemed upset that
YOU didn't notice the flaw and wanted to know about adhesion and durability of patches vs. you're now saying you will explain it all to the customer and do what they request. Personally, I don't think it matters much when you found the mistake..... you found it and in my opinion, my customers rely on me or our guys to get the job done right.
Sorry to repeat myself, but I would think if someone ordered a new banner, it should come through that way, not patched.
All of the noise you're giving us about you didn't know this or that has nothing to do with anything..... the one simple fact remains.
The banner is wrong. All the baggage about software this and adhesion that, doesn't mean a hill of beans. In the end, a professional will provide a finished product, not patched. Besides, a 4' x 10' banner probably costs more than any shoes you've ever bought and probably cost as much as many people spend on four tires for their vehicle, if you're charging correctly.
