Revenue Recognition [Abstract]
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition The Company’s revenues are primarily from the sale of identification solutions and workplace safety products that are shipped and billed to customers. All revenue is from contracts with customers and is included in "Net sales" on the condensed consolidated statements of income. The Company considers the purchase orders, which in some cases are governed by master sales or distributor agreements, to be its contracts with customers. For each contract, the Company considers the commitment to transfer products, each of which is distinct, to be its identified performance obligations. Timing The majority of the Company's revenue is earned and recognized at a point in time through ship-and-bill performance obligations, when control of the product is transferred to the customer, which typically occurs upon shipment or delivery to the customer, depending on freight terms. To determine when control has transferred, the Company considers if there is a present right to payment; and if legal title, physical possession, and the significant risks and rewards of ownership of the asset has transferred to the customer. Once a product has shipped or has been delivered, the customer is able to direct the use of, and obtain substantially all of the remaining benefits from, the asset. Measurement Revenue is measured as the amount of consideration the Company expects to be entitled to in exchange for the transfer of product, which is generally the price stated in the contract specific for each item sold, adjusted for the value of expected returns, discounts, rebates, or other allowances offered to the Company's customers as a reduction of the transaction price. Certain discounts and price assurances are fixed and known at the time of sale. Expected returns and other allowances are variable and are estimated using the expected value method based upon historical experience. Rebates offered to customers are retrospective and typically defined in the master sales or distributor agreements, and therefore are recorded using the most likely amount method based on the terms of the contract. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Payment Terms While the Company’s standard payment terms are net 30 days, the specific payment terms and conditions in its customer contracts vary. In some cases, customers pay for their goods at time of shipment or upon delivery; in other cases, after appropriate credit evaluation, an open credit line is granted and payment is due in arrears. Contracts with payment in arrears are recognized in the condensed consolidated balance sheet as accounts receivable. Warranties The Company offers standard warranty coverage on substantially all products that it sells, and accounts for this standard warranty coverage as an assurance warranty. As such, no transaction price is allocated to the standard warranty, and the Company records a liability for product warranty obligations at the time of sale to a customer based upon historical warranty experience. The Company also sells extended warranty coverage for certain products, which it accounts for as service warranties. In most cases, the extended service warranty is included with the purchase of the product. In applying Topic 606, the Company considers the extended service warranty to be a separate performance obligation in the contract and allocates a portion of the transaction price to the service warranty based on the estimated stand-alone selling price. Under Topic 606, the extended warranty transaction price is initially recorded as deferred revenue on the consolidated balance sheet and recognized on a straight-line basis over the life of the service warranty period. The deferred revenue is considered a contract liability as the Company has a right to payment at the time the product with the related extended service warranty is shipped or delivered and therefore, payment is received in advance of the Company's performance. The balance of contract liabilities as of April 30, 2019, was $2,791. This also represents the amount of unsatisfied performance obligations related to contracts that extend beyond one year. Of this amount, the Company expects to recognize 48% by the end of fiscal 2020, an additional 25% by the end of fiscal 2021, and the balance thereafter. Upon adoption of Topic 606, at the beginning of fiscal 2019, the contract liability balance was $2,796. The current portion of contract liabilities and the non-current portion are included in “Other current liabilities” and “Other liabilities," respectively, on the consolidated balance sheet. During the three and nine months ended April 30, 2019, the Company recognized revenue of $315 and $937, respectively, that was included in the contract liability balance at the beginning of the period, which was from the amortization of extended service warranties. Practical Expedients With the exception of the performance obligations related to the extended service warranties, the Company's contracts have an original expected duration of one year or less. As a result, the Company has elected to use the practical expedient to not disclose its remaining performance obligations for contracts that have an original expected length of one year or less. The Company applied the portfolio approach to its ship-and-bill contracts that have similar characteristics as it reasonably expects that the effects on the financial statements of applying this guidance to the portfolio of contracts would not differ materially from applying this guidance to the individual contracts within the portfolio. As the Company’s product sale contracts and standard payment terms have a duration of less than one year, it uses the practical expedient applicable to such contracts and does not consider the time value of money. Sales, use, value-add and other similar taxes assessed by governmental authorities and collected concurrent with revenue-producing activities are excluded from revenue. The Company accounts for shipping and handling activities that occur after control of the related products transfers to the customer as fulfillment activities and are therefore recognized as revenue at time of shipping. The Company expenses incremental direct costs of obtaining a contract (e.g., sales commissions) when incurred because the amortization period is generally twelve months or less. Contract costs are expensed in "Selling, general, and administrative expenses" on the condensed consolidated statements of income.

The Company’s revenues are primarily from the sale of identification solutions and workplace safety products that are shipped and billed to customers.
