# Tikzposter: Long list of authors breaking in two lines

I have a problem with a long list of authors. I don't want to beak the name between last name and given name. What I mean is shown for Author "AuthorForThis ABCeAAAAAAAA1" How can I avoid this?

Wishes, Mike

And here is a screenshot:

• You could create the titleblock by hand, with all the freedom you need. Unfortunately, this is currently not covered by How to customize my titlepage. – Johannes_B Feb 12 '17 at 15:56
• I think all you want for this is to use a non-breaking space between the two parts of the author name, i.e. \author[1]{AuthorForThis~ABCeAAAAAAAA1} – Dai Bowen Feb 12 '17 at 16:01
• Yes, this is working. The tilde makes it acceptable. – Mike1993 Feb 18 '17 at 11:41

I think all you want for this is to use a non-breaking space between the two parts of the author name, i.e. \author[1]{AuthorForThis~ABCeAAAAAAAA1} using ~ rather than will produce a non-breaking space, preventing a linbreak occuring between the first and second names (see When should I use non-breaking space? for example for a bit more on the usefulness of the non-breaking spaces).

Personally i find the codde very very complicated. Titles often need some manual adjusting, especially for a poster, you can do it b hand more easy.

• Thanks for answering. I have 3 additional questions: (1). what does the "*" in "\vspace*{1em}" do? (2). Is it possible to use your suggestions for author and title if I don't use a block as header? (3). How can I adjust the image in x and y direction? – Mike1993 Feb 13 '17 at 19:12
• @Mike1993 @1) it was in your code, i didn't fiddle with it. @2) not sure what you mean @3) textpos, maybe simpler. That would be a new question. :-) – Johannes_B Feb 13 '17 at 19:56
• @Mike1993 The asterisk does one thing: Add space, no matter what. Without the asterisk: add space, but only, if we aren't at the beginning of a page. – Johannes_B Feb 13 '17 at 19:57
• It's a while I made this. Thanks for explaination regarding to the *. – Mike1993 Feb 14 '17 at 7:29
• To (2): In the real template I haven't a block around authors and title like we see it in the MWE and in your code, Johannes. I didn't use a explicit block in my MWE, but you do. Therfore, I need to know how I can use your code (the author/title part) without a block around it. I thought, it wouldn't work any other way than using this maketitle etc. thingy. – Mike1993 Feb 14 '17 at 7:32
