Custom mugs: which decoration method keeps your logo looking good?
Three questions drive the choice: washing, artwork and recipients.
Dishwasher-safe: the mug, or the print?
According to a promotional products supplier, a "dishwasher-safe" label may cover the product rather than the print; commercial dishwashers can wear down even items listed as dishwasher-safe, and wraparound or near-rim prints may fade sooner; light colours fade before dark ones or engraving [1]. On a forum, sublimation practitioners report designs washing out after repeated cycles [2]; a printer that lists its mugs as dishwasher-safe still suggests the occasional hand wash [3]. Say where the mugs will be washed and ask for care instructions that cover the print.
Your artwork points to the method
Photo or full colour: according to a print-on-demand company and a distributor, sublimation allows unlimited colours and wraparound photos [4][5], but needs a mug with a polymer coating made for the process [4]. Logo in one or two solid colours: the same company says screen printing gives opaque colours and holds up to daily use when the ink suits the glaze and is fully cured [4], two points to have confirmed. Understated look: laser engraving gives a single-tone result with no ink [4].
A promotional products supplier and a distributor note that a mug's imprint area, smaller and more curved than on a flat item [7], is set by the product [5]: have a compact version of your logo ready.
What drives the price
A U.S. promotional products distributor ranks screen printing among the most economical methods, and sublimation and engraving among the most expensive [5]. According to a printer, each screen-printed colour needs its own screen (fewer colours, lower costs), but the unit cost drops sharply with volume, while sublimation is well suited to short full-colour runs [4]. Another distributor notes that a wraparound or two-sided design can add setup charges [6].
A mug people reach for in the morning
In a study by ASI, the U.S. promotional products industry association, on drinkware (ceramic mugs included), 87% of respondents said they would keep such an item because it's useful, and over three quarters that they'd use it at least once a week [8]. Yet a participant in a professional forum and a distributor that sells other items, without citing a study, describe fatigue with logo mugs, which they say pile up in office cupboards [9][10]. So give mugs to people who drink coffee or tea at work, and invest in both the mug and the artwork so it gets picked over the others.
Microwave use and compliance
According to appliance manufacturer Wolf, dishes with metallic paint or trim don't belong in the microwave [11]; according to a printer, neither do metal or enamel mugs [4]. For the office, skip gold, silver and enamel-on-steel.
In Canada, a regulation limits how much lead and cadmium can leach from ceramic or glass cups and mugs whose glaze or decoration contains them [12]. Compliance is the industry's responsibility [13], and some countries don't set limits as strict [14]: for imported mugs, ask for a declaration of compliance with the Canadian regulation.
Écran Blanc's advice
For an office kitchen, a ceramic mug with no metallic decoration and an engraved or dark-coloured logo is often a good starting point. For a gift featuring a photo, go with sublimation on a mug made for it, then check the logo placement on the proof.
