This [overprint colors issue] is a huge, glaring omission.
And one that I didn't realize existed. (Clearly, I haven't been using Affinity software for commercial printing.) For reference, I have been involved in print design for many years and have designed everything from newspaper ads to books with enormous print runs on offset, web and digital. I have traveled across the country on multi-day press checks.
My affinity for Affinity is, in part, due to my loathing for Adobe and their rental model. I imagine this is true for many of the folks here. I have happily supported and promoted Affinity/Serif for offering a "viable alternative" to Adobe. But I may have to rethink this as this alone makes the software non-viable for anyone involved in print. Having to create multiple versions of the same color to have it overprint is ludicrous makes for a completely unworkable workflow. Overprinting should always be available to set on the object level. Always. Period.
Serif/Affinity Team... Please take this seriously. We are all rooting for you to be David in a Goliath industry. If you don't get these absolute basics right, you will never have the commercial success that you, and us, want you to have.
